Pushed it too hard for too long.

Considering that one branch of my family runs towards joint and spinal issues, it might not have been the best of ideas to power lift, or pick a job that involved picking people up in awkward conditions. Or a martial art that involves hitting the ground hard and repeatedly.

Yeah. So, while I would have had the same issues eventually, I likely would have had another ten to fifteen years before it got bad with different choices.

Don't really regret much of it though.
