My BP is 80 / 120 most of the time. My blood sugar levels are 80 to 120 fasting and PP. creatinine is 0.8 for last 3 years after having stones for 3 years in a row before that. liver is perfect. I played badminton 4 to 6 hours a day about 1 year back. These days I play only once in a month. I do not find my stamina going down by not being regular. Rather I feel better now.
