I was just diagnosed a few weeks ago, but in learning about POTS, I realize how long I have had it. I, too, remember back to my days in school... and I am now 53~ and gym teachers telling me to work harder to keep up, especially when running laps. I always wondered how it was that I was always the last one, the slowest one, etc., and wondered how so little exercise could make me feel so badly when everyone else was going, going, going. You know, it's almost funny, but one of the things I would love to do is walk a long distance. I'm not talking five miles... I'm talking across the state. I've read books about people on long walks, and it sounds so exciting~
