I need to get in shape too. I hear you though about not planning to do physical work and then there you are right in the middle of it. I often ask why I bothered going to college when I find myself crawling around on the floor in my dress clothes connecting or disconnecting someones computer...
Lol. I hear you , but it also keeps you grounded. Never lose your roots and doing mundane things like disconnecting a computer sounds stupid, but it is all part of the service. I do loads of things that I shouldn't as well, but I just do it.
