I will never get bored of the intellectual stimulace of my job, but yes, I did start to yearn for something more physical. Having kids pretty much solved that desire for me. I'm now a full time roboticist and a part time cook, people mover, negotiator, lab manager, construction foreman, fitness coach, gym spotter, goalie, wanderer, professional wrestler, cleaner, etc.
I'm surprised every week by what it's like to be a parent. I never expected it to round my life out in such a healthy way, both mentally and physically. Not just because I have offspring but because I'm doing a ton of things I haven't done in years, decades.
