Almost 48 and a curmudgeon in training...
Five foot 9.5, down to 150 pounds after creeping up to 160 and adopting a lower carb diet.
Recent physical showed a relaxed heart rate of 55 and bp of 105/79, and enviable cholesterol numbers which is quite good for a guy who has been forced into a more sedentary lifestyle but I do ride 80km to 100km a week.
