The act of retiring to do nothing is so foreign to me. I take long sabbaticals from employment so I can actually work on harder problems and unfamiliar domains I'd struggle to do professionally if I could even get hired at all to do for money. That and spend more time on my physical fitness while still being able to sleep enough and study other things. Retirement where people just shut down is no different than a scheduled form of burnout.
