I am exactly like you in this regard, and basically it is why I sold my very nice mountain bike about 5 years ago. I knew I could never bunny hop or get over a big log, and I often ended up walking a lot. Part of it was skill and part was just being a wuss. I am not weak compared to other 62 year olds, but for the life of me, I could not figure out how to do this stuff and stay upright. I love being in the woods, so it was sad. I am getting a bit interested in gravel road riding (would have to travel for this) or even to ride some tamer trails, but that would require a new bike now. I may be getting a fat bike in the fall, so that would make me feel secure, although I would need something else for gravel riding.
