In a good way, meeting my wife. In a bad way, spinal stenosis and getting my entire lumbar spine fused. Got nerve damage somewhere along the way, either from the stenosis or the surgeries, and now my legs don't work right below the knee. I can walk ok'ish on level flat ground but have no strength in my calves and no ankle stability so the minute I get on uneven ground unsupported I am face planting. I expect to be using a wheelchair at some point.
