In an cause to slow down — and even halt — the age process , scientist are progressively turning their aid to the various extraneous and intragroup ingredient that give ascent to it . As this new video byAsapSCIENCEshows , we ’re all slaves to a biologic clock that ’s been tick away since the here and now we were give birth — and it ’s setting a hard limit on how onetime we can become .
In this “ scientific discipline of senescence ” video , Mitchell Moffit and Gregory Brown reexamine the problem triggered by cellular damage , the result of ever - shortening telomere duration . Eventually , our cells lose their function and perish . We experience this as senescence , and ultimately , last .
Interestingly , these cellular replication limits may prevent certain cancers from lift .
It ’s also significant to take note that Moffit and Brown are grossly oversimplifying the aging process . Cellular ageing is understandably an important factor , but not the only one . Gerontologist Aubrey de Grey has isolatedat least seven factor responsible for for human senescence :
The loss of cells that we need
The accumulation of cells that we do n’t necessitate
DNA mutations inside the cell nucleus
DNA mutation inside the cell ’s mitochondria
The accruement of “ junk ” in spite of appearance of cellular phone
The accumulation of “ dust ” outside of cell
The shaping of cross - linked protein outside cells
By framing it this direction , de Grey and others are hoping to systematically tackle these various problem in an effort to slow down the aging appendage , and ultimately achieve so - callednegligible senescence .
