Ageing drive has long way to go

Prof Christina Doyle of Xeno Medical, a medical devises company, told the BBC making and testing each of foreseeable replacements to achieve “50 active years after 50” would take 30 to 50 years. Understanding the brain, and some of its parts age earlier than a leg, and developing replacements will certainly take longer.

It would seem then that “50 active years after 50” would come earlier than “50 clear thinking years after 50”. Hence, the likes of Madame Jeanne Calment of France who died at 122 will strut and gyrate hips, in haphazard awareness. It will be fun, nonetheless.
