One consideration is how much use, and abuse, your body has had up to age 40. Hundreds of thousands of pushups or straight bench may have set some damage in the shoulders already. Seems from reading others comments, both here and other sites, that individuals vary in ability to handle, long term, above 50-55#'s.
I "plus one" the above comments. Around now, mid spring, I start really practicing again. By end of season, January 31st, I can pull 45 pounds like it is a toy. I am 53. However, I need to go slow, mindfully.
Going higher, once again, on draw weight, for flatter trajectory when desert, grassland hunting. I will have to be slow on building up to volume as I have ignored warnings and had archer's elbow before. I have some exercise bands that I pull when I can not get to the hills to practice. That helps.
