FWIW, Mine regularly gets to 185, I've seen it in the low 190s a few times. I do a lot of HIIT training and get the heart rate up pretty high for several intervals. I'm 37 and have had the same exercise pattern now for almost a year. I haven't noticed any ill effects from the higher heart rate, or that it wears me out. I have worn myself out from exercise, but that was from excessive time, not a high heart rate periodically during the exercise.
