You've got me only by a couple years Tom, but I certainly understand your situation.
I have done physical work my entire life and still have decent upper body strength for my age, but a far cry from 10 years ago. Still bowhunting here with my OLD Browning compound which I have set and tuned at 53 lbs tipped with 100gr Slick Tricks.
Exclusively need just one shot which almost always gets a pass through.
Don't be afraid to lower the poundage, so long as you have it tuned properly for that reduction.

PS. Bought a new Ten Point crossbow this past spring just in case! LOL.
