I have two BIG ones: I volunteered for service in the U.S. Army in 1970, during Vietnam (NOT a good idea), and I got married after I got home. I survived Vietnam and have been divorced long since, but the marriage may have come the closest to killing me in the end. I do have two beautiful, exceptional grown daughters though, and make no complaint about that.
After over half a century on this Earth, I discovered that I really, really like repairing PCs, and I continue to enjoy that enormously. So all told, it's all been survivable to this point.
