I share the point of pointless existence. Purely theoretically damage to DNA can be undone and process reversed or significantly extended. 30 years from now is relatively a lot having in mind the acceleration of science and technologies. Just look where we were in 1990's... and it's picking up speed.

There is always a chance of accidental discovery too if enough people work on the issue. Just like with penicillin, almost accidental breakthrough and hundreds of millions lives saved.

And naturally things can go south in totally different direction, but this is the topic i like and keep researching it, love biochemistry it at least helped me to create an efficient recipe to help with my hangover.
