As a man approaching 50, I desperately hope this is true.
Unfortunately I have to retract my above statement, I checked https://www.reddit.com/r/Futurology/comments/3fri9a/ask_aubrey_de_grey_anything/ .
Q:Does it speed up the development timeline at all? A:Aubrey de Grey, SENS[S]: A lot, yes.
No concrete timeframe, but he also gives estimates:

Seems as if he gives a 50yo has about 50% chance to be around when SENS comes.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
