We like to think of romantic feelings
0
7051
1843
Volimo da mislimo da su romantična osećanja
00:08
as spontaneous and indescribable things that come from the heart.
1
8918
4115
spontana i neopisiva i da dolaze iz srca.
00:13
But it's actually your brain
2
13057
1565
Ali u stvari vaš mozak
00:14
running a complex series of calculations within a matter of seconds
3
14646
4099
radi složene proračune u sekundi
00:18
that's responsible for determining attraction.
4
18769
2714
koji su odgovorni za privlačenje.
00:21
Doesn't sound quite as poetic, does it?
5
21507
2103
Ne zvuči baš poetično?
00:23
But just because the calculations are happening in your brain
6
23634
3154
Ali, iako se ovi proračuni obavljaju u vašem mozgu,
00:26
doesn't mean those warm, fuzzy feelings are all in your head.
7
26812
3322
to ne znači da su sva ta prijatna osećanja u vašoj glavi.
00:30
In fact, all five of your senses play a role,
8
30158
2493
U stvari, svih 5 čula ima ulogu.
00:32
each able to vote for, or veto, a budding attraction.
9
32674
3556
Svako od njih glasa za ili protiv privlačnosti.
00:36
The eyes are the first components in attraction.
10
36949
2350
Oči su prva komponenta kod privlačnosti.
00:39
Many visual beauty standards vary between cultures and eras,
11
39323
3769
Mnogi vizuelni standardi lepote
variraju među kulturama i razdobljima,
00:43
and signs of youth, fertility and good health,
12
43116
2525
a znaci mladosti, plodnosti i dobrog zdravlja,
00:45
such as long lustrous hair,
13
45665
1793
kao što je duga, sjajna kosa,
00:47
or smooth, scar-free skin,
14
47482
2345
ili glatka koža bez ožiljaka,
00:49
are almost always in demand
15
49851
1437
skoro uvek su poželjni
00:51
because they're associated with reproductive fitness.
16
51312
2897
jer su u vezi sa reproduktivnom sposobnošću.
00:54
And when the eyes spot something they like,
17
54233
2199
Kad oči primete nešto što im se sviđa,
00:56
our instinct is to move closer
18
56456
2118
naš instinkt je da se približimo tome
00:58
so the other senses can investigate.
19
58598
2020
da bi druga čula mogla da ispitaju stvar.
01:00
The nose's contribution to romance
20
60642
2153
Doprinos nosa romansi nije samo
01:02
is more than noticing perfume or cologne.
21
62819
2769
prosto primećivanje parfema ili kolonjske vode.
01:05
It's able to pick up on natural chemical signals
22
65612
2601
Nos može da uhvati prirodne hemijske signale
01:08
known as pheromones.
23
68237
1542
zvane feromoni.
01:09
These not only convey
24
69803
1277
Oni ne samo da prenose
01:11
important physical or genetic information about their source
25
71104
3425
važne genetske informacije o izvoru,
01:14
but are able to activate a physiological or behavioral response in the recipient.
26
74553
4995
već mogu da aktiviraju fiziološki
ili bihejvioralni odgovor kod primaoca.
01:19
In one study, a group of women
27
79572
2354
U jednoj studiji, grupa žena u različitim momentima ovulacije
01:21
at different points in their ovulation cycles
28
81950
2222
01:24
wore the same T-shirts for three nights.
29
84196
2305
nosila je iste majice tri noći.
01:26
After male volunteers were randomly assigned
30
86525
2456
Pošto su muški dobrovoljci nasumično izabrani
01:29
to smell either one of the worn shirts, or a new unworn one,
31
89005
3968
da pomirišu bilo koju od nošenih
ili nenošenih majici,
01:32
saliva samples showed an increase in testosterone
32
92997
3744
više testosterona su imali uzorci pljuvačke
01:36
in those who had smelled a shirt worn by an ovulating woman.
33
96765
3742
onih koji su mirisali majicu žene u ovulaciji.
01:40
Such a testosterone boost
34
100531
1644
Ovaj skok testosterona
01:42
may give a man the nudge to pursue a woman
35
102199
2545
možda daje muškarcu podsticaj da se približi ženi
01:44
he might not have otherwise noticed.
36
104768
1739
koju inače možda ne bi primetio.
01:47
A woman's nose is particularly attuned
37
107028
2131
Nos žene je posebno prilagođen
01:49
to MHC molecules, which are used to fight disease.
38
109183
3933
za MHC molekule,
koji služe za odbranu od bolesti.
01:53
In this case, opposites attract.
39
113140
2453
U ovom slučaju, suprotnosti se privlače.
01:55
When a study asked women to smell T-shirts that had been worn by different men,
40
115617
4415
Kada je od žena zatraženo da pomirišu majice
koje su nosili različiti muškarci,
02:00
they preferred the odors of those whose MHC molecules differed from theirs.
41
120056
5096
dale su prednost mirisima onih
čiji su se MHC molekuli razlikovali od njihovih.
02:05
This makes sense.
42
125176
1202
To ima smisla.
02:06
Genes that result in a greater variety of immunities
43
126402
2683
Geni koji imaju više vrsta otpornosti
02:09
may give offspring a major survival advantage.
44
129109
2610
mogu dati potomstvu veću prednost u preživljavanju.
02:12
Our ears also determine attraction.
45
132552
2084
Naše uši takođe određuju privlačnost.
02:15
Men prefer females with high-pitched, breathy voices,
46
135302
3218
Muškarci više vole viši ženski glas, sa više daha
02:18
and wide formant spacing, correlated with smaller body size.
47
138544
4296
i sa većim rasponom između formanata,
što je u vezi sa sitnijom građom.
02:22
While women prefer low-pitched voices with a narrow formant spacing
48
142864
4428
Dok žene vole dublje glasove
sa manjim rasponom između formanata,
02:27
that suggest a larger body size.
49
147316
1656
što ukazuje na krupniju građu.
02:29
And not surprisingly,
50
149694
1295
I što nije iznenađujuće,
02:31
touch turns out to be crucial for romance.
51
151013
2493
dodir je izgleda presudan za romansu.
02:33
In this experiment, not realizing the study had begun,
52
153530
3666
U ovom eksperimentu,
ne znajući da je posmatranje počelo,
02:37
participants were asked to briefly hold the coffee,
53
157220
3754
učesnike su zamolili da pridrže kafu,
02:40
either hot or iced.
54
160998
1724
vruću ili ohlađenu.
02:42
Later, the participants read a story about a hypothetical person,
55
162746
3504
Kasnije, učesnici su pročitali priču
o nekoj hipotetičkoj osobi
02:46
and were asked to rate their personality.
56
166274
2108
i pitali su ih da ocene njegovu ličnost.
02:48
Those who had held the hot cup of coffee
57
168406
2413
Oni koji su držali vruću šoljicu kafe
02:50
perceived the person in the story as happier,
58
170843
2871
doživeli su osobu u priči kao srećniju,
02:53
more social, more generous and better-natured
59
173738
3794
društveniju, darežljiviju i boljeg karaktera
02:57
than those who had held the cup of iced coffee,
60
177556
2690
nego oni koji su držali hladnu šolju kafe,
03:00
who rated the person as cold, stoic, and unaffectionate.
61
180270
3524
koji su ocenili osobu kao hladnu i ravnodušnu.
03:04
If a potential mate has managed to pass all these tests,
62
184761
3086
Ako je potencijalni partner prošao
sve ove testove, ostao je još jedan:
03:07
there's still one more:
63
187871
1483
03:09
the infamous first kiss,
64
189378
2577
čuveni prvi poljubac,
03:11
a rich and complex exchange of tactile and chemical cues,
65
191979
4505
sočna i složena razmena
taktilnih i hemijskih znakova,
03:16
such as the smell of one's breath,
66
196508
1678
kao što je miris daha
03:18
and the taste of their mouth.
67
198210
1392
i ukus usta.
03:20
This magical moment is so critical that a majority of men and women
68
200094
3934
Ovaj magični trenutak je tako važan
da je većina muškaraca i žena
03:24
have reported losing their attraction to someone
69
204052
2301
rekla da je privlačnost prema nekome oslabila
03:26
after a bad first kiss.
70
206377
1663
posle lošeg prvog poljupca.
03:28
Once attraction is confirmed, your bloodstream is flooded
71
208762
2910
Kada se privlačnost potvrdi,
vaš krvotok je preplavljen
03:31
with norepinephrine,
72
211696
1509
norepinefrinom
03:33
activating your fight or flight system.
73
213229
2288
koji aktivira vaš sistem za borbu ili bežanje.
03:35
Your heart beats faster,
74
215541
1598
Srce vam lupa jače,
03:37
your pupils dilate,
75
217163
1346
zenice se šire
03:38
and your body releases glucose for additional energy,
76
218533
3090
i telo oslobađa glukozu zbog dodatne energije,
03:41
not because you're in danger but because your body is telling you
77
221647
3128
ne zato što ste u opasnosti,
već zato što vam telo govori
03:44
that something important is happening.
78
224799
1810
da se dešava nešto važno.
03:46
To help you focus,
79
226633
1171
Da vam pomogne
03:47
norepinephrine creates a sort of tunnel vision,
80
227828
2478
da se usredsredite,
norepinefrin stvara neku vrstu tunelske vizije,
03:50
blocking out surrounding distractions,
81
230330
2271
blokira sporedne stvari,
03:52
possibly even warping your sense of time,
82
232625
2398
možda čak menja i vaš osećaj za vreme
03:55
and enhancing your memory.
83
235047
2082
i pojačava pamćenje.
03:57
This might explain why people never forget their first kiss.
84
237153
2958
To možda objašnjava zašto ljudi
nikad ne zaboravljaju prvi poljubac.
04:01
The idea of so much of our attraction
85
241000
2034
Ideja da na naše međusobno privlačenje
04:03
being influenced by chemicals and evolutionary biology
86
243058
3241
toliko utiče hemija i evoluciona biologija
04:06
may seem cold and scientific rather than romantic,
87
246323
2692
možda izgleda više hladna i naučna nego romantična, ali kada
04:09
but the next time you see someone you like,
88
249039
2296
sledeći put vidite nekog ko vam se sviđa,
04:11
try to appreciate how your entire body is playing matchmaker
89
251359
3961
pokušajte da shvatite kako vaše telo igra ulogu u odlučivanju
04:15
to decide if that beautiful stranger is right for you.
90
255344
2898
da li je taj divni stranac prava osoba za vas.
