Agreed.<p>I moved furniture as a young man, and that was only in 8 hours stints at the longest.  At the end of the day, my body seemed to rebel against me if I even slightly exerted myself.<p>My current 60+ work weeks are mainly spent sitting, and although I&#x27;m tired at the end of the day, it&#x27;s nowhere near as taxing as moving furniture was (and I&#x27;m older).
