After 35 you've probably got a kid or two, a mortgage and all that comes with it. You definitely don't have as much potential time to put towards whatever. I don't care how much better you think you got at time management in response to increased demands on it, but you can't argue that you just have less of it day to day.
I'm making plans to test out how far this goes, will try to report back.
Does life end at 35? Not for this specific accomplished scientist.
