This is some serious research being done in China, identifying genes to modify to extend life.

We are almost ready to connect the dots. We have CRISPR that is becoming a more and more sophisticated gene editing tool. And we know that one of the primary mechanisms of aging is the “senescent” cell (sometimes called a “zombie” cell) that no longer functions but is not dead, and which secretes chemicals that interfere with cellular functions, making you age faster.

This is a good step, have a look.
