Have we humans been doing aging wrong? Whats the logic of being born only to start dying ?

what if TRUE aging consists in becoming stronger, better, more beatiful, for each decade we age? Technology, spread of plants and seeds, moss and algae... All evolution as a whole, everything gets better with age. What if a Celibate (no wet dreams) man -who dont exist anymore- would be better at 120 years old than at 30? look better, be better, perform and think better.
