Aha (one of many such moments here). Airline seats... designed specifically to make travelers appreciate hotel beds. I dutifully follow the instructions of my Doc and plug myself in every night even thought I feel no magical change in my energy level. My son suggested that perhaps at my advanced age (59) I may be suffering from "low T". This of course appeals to my kinky side, encouraging my mind to develop exciting new ways to stimulate my testosterone production factory. Hmmmmm, electricity, stretching, strategic accupuncture, compression??? Sorry, just dreaming.
