When you get to senior...and past shelf life
Seems that are more busy than before as "pre-retired"
The body adjusts sleeping patterns.
I sleep regularly as clockwork 5 hours...so if I turn in at 2 am will wake up at 7 am.
Spokeshave at 76.
Trump has always slept little, I remember an article quoting his butler at Mar A Lago, who retired quite a few years ago. Trump slept 4-5 hours a night, gets up early. And the no booze, drugs, cigarettes, even coffee - EVER - must help his health.
Funny thing, that. 5 - 5.5 hours does it for me at 67.
