I'd also be bragging if I could get mine down that low. I was in the higher 30's when I was younger (a lot younger...) but never passed below 37. Now I'm happy when I'm in good enough condition to get below 50. It turns out there are some odd costs to having such low heart rates - at least for bicycle racers. One is an increased occurence of blood clots in the lower legs during long periods of inactivity - specifically long airline flights after hard physical activity. I don't remember all the physiology but as the blood thickens due to dehydration (really common on long flights) the low heart rate, sitting position, no movement, etc. combine to result in clots. Keep those legs moving! Howard Snell
