My wife is on that back end of menopause and her body is slowly changing. I noticed the other day that her butt has pretty much flattened. Mine is round and pert. This is the advantage time provides; we continue to move in a feminine direction while our cis counterparts are slowly losing their curves and softness. It levels the playing field a bit.
On the subject of electronics, I spent years working on cars, first on audio systems, then general wiring on the manufacturing end, then restoration. But a few years later, I spent a few years doing small-volume manufacturing, mostly at home. I would get up every day and solder circuit boards and other assemblies. I started by doing everything with a soldering iron, then bought a solder pot, then ended up farming out the stuffing/soldering. I learned a bit of repair, working with a meter and logic probe, but I never was a proper "tech." I'm extremely good at troubleshooting, but I never got fully trained in theory - I was too distracted by other things.
Despite being somewhat ADHD, I really enjoyed the repetitive work of soldering. I think I have a hyper-attentive/focus condition that allows me to spend hours doing these sorts of things. It's why I feel that performing electrolysis will be attractive to me.
