Did quite a few 30 plus hours without a nap plowing and sanding, didn't feel tired at the time, but was in my twenties...lol

Now I'm ready for a nap after about 6 hours....

You don't realize what your capable of unless you do it.

If single handed trans Atlantic boat deliveries count ( as ya don't leave your workplace before its done ) then 39 days is my longest non stop work time. from Arrecife Brasil to Cape town South in a 33 foot Hustler racing sail boat .... I sailed it 4 days before that trip to Arrecife from Grand Canaria and that took 24 days all by my lonesome.

Too much. I want to retire.. shoulda went union with 8 hour days.
