The problem with being practiced
... is that it takes more to really push yourself. If you run regularly, what it takes to feel really tired and spent goes up. If you downhill ski a lot, the steepness or challenge of a run needed to make you feel the thrill of pitting yourself against the mountain increases.
And if you periodically stuff yourself, even if not all that regularly, it takes a lot more to really feel you are at your limit.
In other words, at lunch today I went to a big buffet restaurant near my work, stayed for an hour, and kept track of the approximate calories I was eating (they have signs at each serving dish). I had about 3500 calories -- well more than my recommended daily amount, and all within an hour -- and feel ... full. mostly. Definitely not FULL, not waddling out full, not hard to breath full, not even "I couldn't do another full plate" full.
I wish I hadn't had to get back to work, taking another 15-20 minutes and eating some more of all my favourites might have gotten me there? Hard to be sure.
And I'm not a regular stuffer, maybe 3-4 times a year I go this hard, but I've also had such incidence for a lot of years, and had some years where it was a lot more common. I guess I really stretched out my capacity, and still do it often enough for my capacity not to shrink too much.
Anyway, I'm annoyed that 3500 calories worth of food is apparently not enough to make me feel I'm near my limit these days. Not sure what I'm going to do the next time that I really need a feedee fix.
