Well... enjoy it, be thankful for it, and hope you don't end up with a chronic, life-changing illness. My draw weight capability dropped 24# in ONE DAY about ten years ago.
My 47#er is my usual "heavy" bow these days, but I'm holding onto trad archery, kicking and screaming, until it is pried from my fingers.
My goal used to be a bow over 80#... now it is simply to keep shooting. I still enjoy the HECK out of it, as I know you do your heavy bows.
Sometimes a lifestyle, sometimes genetics, sometimes athletic training... and sometimes the evidence of destiny (or God's will!)
Shoot straight, and enjoy!
