I am 83 and don't want to stop shooting. Have a 80% torn right rotator cuff which my doc doesn't think I should fix. He said I should just do exercises. I do them daily. I shoot right handed.
I shoot 38# and 40#. The most weight I ever shot was 53#. I took 22 whitetails, a wild boar and a javelina with a 45#. An elk with the 53. I can shoot about 50 arrows comfortably with the 38#. Good enough for a trad shoot!
Hope that helps
