Nthawi ya nyengo ikuyimira kuchuluka kwa nthawi yomwe munthu wakhala ali moyo. Mwa kuyankhula kwina, chiwerengero cha masiku, miyezi kapena zaka zomwe munthu akhala akusintha sichimasintha , mosasamala kanthu momwe moyo ulili wathanzi - ngakhale mmodzi wodzazidwa ndi zizoloŵezi zabwino zochita masewera olimbitsa thupi ndi zakudya - akukhala.
Aliyense ali ndi zaka zosiyana. Anthu ena amawoneka kuti akula msanga kwambiri, pamene ena akukalamba mofulumira kwambiri.
Tonse takhala tikukumana ndi munthu nthawi yoyamba yemwe amaoneka kuti ali wamng'ono kapena wamkulu - kuposa momwe alili.
Kusiyanitsa Pakati pa Zakale Zakale ndi Zamoyo Zakale
Monga anthu, tili ndi zaka ziwiri zosiyana: nthawi ndi nthawi. Mibadwo ya zaka ndi zaka zomwe munthu wakhala ali moyo, pamene zaka za chilengedwe zimayang'ana momwe munthu amaonekera . Zaka za chilengedwe, zomwe zimatchulidwanso kuti ndi zaka zakuthupi, zimaganizira zambiri za moyo, kuphatikizapo zakudya, masewera olimbitsa thupi komanso zizoloŵezi zogona, kutchula ochepa.
Momwe ife timakalamba sitingathe kulamulira. Izi zimakhudza kwambiri chibadwa, koma kafukufuku waposachedwapa amamvetsa momwe ukalamba ungakhudzidwe ndi zinthu zakunja, kuphatikizapo zakudya, zolimbitsa thupi, nkhawa, ndi kusuta. Akatswiri ambiri amakhulupirira kuti zaka zochitika zakale sizikhala zosakwanira chifukwa sizingaganizire zazing'ono izi.

Kafukufuku amasonyeza kuti telomeres ndi DNA methylation zimaseŵera mbali zikuluzikulu pa ukalamba.
Ma telomeres ndiwo nucleotide pamapeto a chromosomes. Amaika mapeto a chromosomes kuti asawonongeke ndi kusakaniza ndi chromosome yapafupi. Mwachidziwikire, ma telomere amachititsa kuti maselo atsatire msinkhu ndi kufa.
Akatswiri a sayansi apeza kuti msinkhu wa nthawi ya munthu, wamfupi ndi ma telomere.
Kafukufuku wina anapeza kuti anthu omwe ali ndi tambala tating'ono kwambiri amakhala odwala msanga kapena amakhala ndi matenda kapena matenda osokoneza bongo. Kafukufuku wina akusonyeza kuti kukhala ndi moyo wathanzi kumatha kuchepetsa ukalamba powonjezera kutalika kwa telomere, uthenga wabwino wa chikhalidwe chathu chokhala ndi zaka zambiri.
Asayansi akugwiritsanso ntchito DNA methylation kuti adziwe zaka zamoyo. Maselo amagwiritsira ntchito DNA methylation pofuna kuteteza majini. Mwa kuyankhula kwina, DNA methylation imatembenuza majini. Ngakhale kuti cholinga chenicheni cha methylation sichidziwika, ndi kofunika kuti chitukuko cha embryonic, maonekedwe a genomic, chromosome chilimbike ndi zina zambiri.
Kafukufuku wina adafuna kudziwa ngati DNA methylation ndi njira yolondola yodziwiratu zaka ndi kusonkhanitsa mitundu 8,000 ya mitundu makumi asanu ndi limodzi (51,000). Zambiri za minofu ndi selo zomwe zidaphunziridwa zinali ndi zaka zofanana ndi zakale. Ena sanatero. Phunziroli linapeza kuti ziwalo zina za m'thupi zimapita mofulumira kuposa ena. Mwachitsanzo, minofu ya m'mawere ndi ena mwa minofu yakale kwambiri m'thupi. Kafukufukuyu anapeza kuti ngakhale ziwalo za m'mawere zathanzi zingakhale zoposa zaka zitatu kuposa thupi lonse la mkazi. Ngati minofu yathanzi imakhala pafupi ndi minofu ya khansa, ili ndi zaka 12 zakubadwa .
Ngati mukufuna kudziwa zaka za chilengedwe, dziwani nokha ndi RealAge , chitsimikizo chokhalitsa .
