00:00:00,000 --> 00:00:00,560


2
00:00:00,560 --> 00:00:07,360
Namuhla, ungabona cishe yonke indawo ezindlebeni
zabantu emsebenzini, lapho behamba nasemidlalweni.

3
00:00:07,360 --> 00:00:15,019
Sikhuluma ngamahedfoni we-Bluetooth angenantambo afana
namahedfoni adume kakhulu angena endlebeni, i-AirPods ye-Apple.

4
00:00:15,019 --> 00:00:21,991
Isindinganiso esingenantambo seBluetooth sivumela
ukudluliswa kwedatha, umculo, amavidiyo noma izithombe

5
00:00:21,991 --> 00:00:26,489
ezindaweni ezifushane, sisebenza ngendlela efana ne-Wi-Fi.

6
00:00:26,489 --> 00:00:31,525
Ngokudala insimu kagesi-magnethi enamafrekhuwensi
aphezulu, lobu buchwepheshe buvumela imodeli

7
00:00:31,525 --> 00:00:35,303
yomthumeli nemodeli yomamukeli ukuthi zixhunywe ndawonye.

8
00:00:35,303 --> 00:00:41,015
Ububanzi obukhulu bushintsha phakathi
kuka-10 no-100 wamamitha, kuye ngomshini.

9
00:00:41,015 --> 00:00:46,563
Umkhakha wamahedfoni afakwa endlebeni uyakhula
ngokushesha futhi lobu buchwepheshe busetshenziswa kabanzi.

10
00:00:46,563 --> 00:00:51,875
Lokhu kunganaki umbuzo wokuthi imisebe
ejulile ngaphakathi kwindlebe – eduze kwengqondo

11
00:00:51,875 --> 00:00:56,893
– inayo muphi umthelela emzimbeni womuntu.

12
00:00:56,893 --> 00:01:05,154
Esicelweni esathunyelwa e-WHO naseZizwe Ezihlangene esashicilelwa
ngo-2019, ososayensi abangama-250 abavela emazweni angaphezu

13
00:01:05,154 --> 00:01:10,727
kuka-40 baxwayisa ngezingozi ezinzima
zezempilo ezibangelwa amahedfoni afana ne-Apple

14
00:01:10,727 --> 00:01:14,626
AirPods nezinye izobuchwepheshe ezingenantambo.

15
00:01:14,626 --> 00:01:22,381
Kukhona ubufakazi besayensi obukhulayo ngokushesha obukhombisa
ukuthi izinkambu zikagesi ezidaliwe yizisetshenziswa

16
00:01:22,381 --> 00:01:30,608
ezingenantambo nezogesi ezifana namaselula, izimasti zamaselula,
i-Wi-Fi, izilawuli zomntwana kanye namahofoni e-Bluetooth

17
00:01:30,608 --> 00:01:35,676
ziyingozi kubantu, ezitshalweni, ezilwaneni nakuma-microbes.

18
00:01:35,676 --> 00:01:43,688
Imiphumela emibi kwezempilo yamaza kagesi i-electromagnetic
ifaka: ukwanda kwengozi yomdlavuza, ukucindezeleka

19
00:01:43,688 --> 00:01:50,680
kwamangqamuzana, umonakalo wofuzo, izinguquko zesakhiwo
nokusebenza kohlelo lokuzala, ukuntuleka

20
00:01:50,680 --> 00:01:58,799
ekufundeni nasekukhumbuleni, izifo zobuchopho,
kanye nemiphumela engemihle ekuphileni okuhle.

21
00:01:58,799 --> 00:02:08,008
Isicelo samazwe ngamazwe siyaqhubeka sithi: "Iziphathimandla
eziningi ezibhekele ukubeka imingcele zihlulekile emsebenzini

22
00:02:08,008 --> 00:02:14,273
wazo wokusungula iziqondiso ezifanele
zokuvikela umphakathi, ikakhulukazi izingane,

23
00:02:14,273 --> 00:02:19,098
ezisengozini enkulu ngenxa yemiphumela yamaza kagesi."

24
00:02:19,098 --> 00:02:26,075
Lolu hlelo lokuthi ubuchwepheshe beBluetooth bunikezwa
ukunakwa okuncane kakhulu, ikakhulukazi ezidlalweni

25
00:02:26,075 --> 00:02:30,961
zezingane, lwabikwa ngumama okhathazekile owayexhumane neKla.TV.

26
00:02:30,961 --> 00:02:35,877
Indodana yakhe eneminyaka emihlanu yadideka
yagcwala amathumba emithambo ye-lymph entanyeni yakhe.

27
00:02:35,877 --> 00:02:41,779
Lokhu kwenza umndeni wacabanga ukukala inani lokukhishwa
kwemisebe kwepeni ethandwa kakhulu yendodana yabo,

28
00:02:41,779 --> 00:02:49,593
i-BOOKii pen – ipeni yedijithali yokurekhoda umsindo engakwazi,
isibonelo, ukwenza isithombe encwadini yezingane sikhulume.

29
00:02:49,593 --> 00:02:56,309
Ikhiphe isignali eqhubekayo ebangeni lama-200,000 kuya
kwama-300,000 microwatts. Ucwaningo

30
00:02:56,309 --> 00:03:04,848
ku-inthanethi lwembule ukuthi, ngokomkhiqizi,
akunakwenzeka ukuvala umsebenzi we-Bluetooth wepeni.

31
00:03:04,848 --> 00:03:12,433
Ngenxa yesipiliyoni sakhe, unina okhathazekile wamangala ukuthi
umkhiqizi akazange aphoqeleke ukwazisa abazali ukuthi

32
00:03:12,433 --> 00:03:21,393
ukusebenzisa ipeni ye-BOOKii kwabeka izingane zabo kulesi
sikhathi somisebe kanye nezingozi zempilo ezihambisana nakho.

33
00:03:21,393 --> 00:03:28,375
Isazi somgogodla esidumile uProfesa Andrew Huberman waseStanford
University School of Medicine ukhombisile

34
00:03:28,375 --> 00:03:35,130
ukuthi hhayi izingane kuphela kodwa nabantu abadala
nabo bayathinteka kubuchwepheshe beBluetooth.

35
00:03:35,130 --> 00:03:40,071
Ucwaningile kabanzi ukusetshenziswa
kwamahhala wezindlebe we-Bluetooth futhi

36
00:03:40,071 --> 00:03:44,136
uxwayisa ngezingozi zempilo ezingase zibe khona.

37
00:03:44,136 --> 00:03:49,436
Wahlushwa yizicubu ze-lymph ezivuvukile ngemuva
kwezindlebe zakhe nokushisa okushubile emzimbeni,

38
00:03:49,436 --> 00:03:53,222
okwakubangelwa ukusebenzisa amahedfoni eBluetooth.

39
00:03:53,222 --> 00:03:58,839
Yingakho ashintshele kumahedfoni anezintambo.

40
00:03:58,839 --> 00:04:02,773
NgokukaHuberman, "ukushisa
nezicubu zemithambo-luvo aziyizihlobo."

41
00:04:02,773 --> 00:04:11,996
Ngenxa yalokhu, ukhathazekile ngezingozi ezingase zenzeke
lapho lezi zindawo ezibucayi zibekwa ekushiseni okuqhubekayo.

42
00:04:11,996 --> 00:04:20,066
Abakhiqizi, abathengisi neziphathimandla zokulawula
amadivayisi omsindo angenantambo bayawunganaki izixwayiso.

43
00:04:20,066 --> 00:04:23,218
Ingabe lokhu kungaba ngenxa yezintshisekelo zezomnotho?

44
00:04:23,218 --> 00:04:33,694
Imakethe yamadivayisi omsindo angenantambo yalinganiselwa
ku-$64.76 billion ngo-2024, kanti ukukhula kwemakethe emhlabeni

45
00:04:33,694 --> 00:04:39,635
wonke kulindeleke ukufinyelela ku-$206.84 billion ngo-2032.

46
00:04:39,635 --> 00:04:45,553
UJames Russell ugcizelela ezinye izingxabano
zezintshisekelo phakathi kwemboni yocingo lweselula nocwaningo

47
00:04:45,553 --> 00:04:49,749
kwezobuchwepheshe bomsakazo efilimini yakhe yedokhumentari.

48
00:04:49,749 --> 00:04:55,096
Ifilimu inika izwi kososayensi
abahlukahlukene, abamele imboni nodokotela.

49
00:04:55,096 --> 00:05:00,983
Phakathi kwezinye izinto, kushiwo ukuthi
ngokuqinisekile kunokungqubuzana kwezintshisekelo

50
00:05:00,983 --> 00:05:05,490
mayelana nokuxhaswa kwezifundo embonini yomsakazo.

51
00:05:05,490 --> 00:05:11,689
Uma ucubungula ucwaningo, kubalulekile
ukucabangela ukuthi ubani owaxhasa lolu cwaningo.

52
00:05:11,689 --> 00:05:19,394
Izindinganiso zomsakazo ezibandakanya amaza aphezulu ziyingxenye
yansuku zonke yempilo yethu, futhi kuyethusa ukuthi

53
00:05:19,394 --> 00:05:26,916
okwamanje azikho nhlobo iziqondiso zamazwe ngamazwe
eziphathelene nomonakalo wezempilo ongapheli noma umdlavuza.

54
00:05:26,916 --> 00:05:31,716
Imihlahlandlela isekelwe kuphela emiphumeleni
yokushisa noma emiphumeleni esheshayo efana nokuzwa

55
00:05:31,716 --> 00:05:34,857
ukuvuvukala kwesikhumba noma ukudlikiza kwebrows.

56
00:05:34,857 --> 00:05:39,223
Akukakayekethwa isilinganiso sokunquma
izingozi zezempilo zesikhathi eside.

57
00:05:39,223 --> 00:05:46,241
Lokhu ngokungangabazeki kusho ukuthi imboni
nososayensi abayithengayo abananhloso yokuvikela

58
00:05:46,241 --> 00:05:52,442
umphakathi ekulimazweni kwezempilo kwesikhathi eside.

59
00:05:52,442 --> 00:05:57,102
Wonke umuntu angasiza ukuvikela
imvelo yakhe ezingozini zezempilo:

60
00:05:57,102 --> 00:06:03,397
Ngokunikeza ulwazi oluphelele mayelana nezingozi
ezibangelwa ubuchwepheshe beBluetooth nezobuchwepheshe

61
00:06:03,397 --> 00:06:08,649
zocingo lweselula, nokungawasebenzisi lapho kungenzeka khona.

62
00:06:08,649 --> 00:06:11,256
Hlala waziswe – lalela futhi kusasa.
