I love climbing, but lets be honest - in later years it is quite brutal on your fingers and overall wrists. Things like osteoarthritis affect climbers too, heck based on some discussion with a doctor doing a lot of ultrasounds of hands its expected that climbers have messed up joints in hands and she could see some damage on mine too (I climb for a decade, in my early 40s).

For every guy climbing till his 70s there are a lot of those who had to stop for reason XYZ much before. If its not this its shoulder, anything in legs, spine and so on. Genes play a huge part too and thats pure lottery.
