My question is if we all get 1.5 billion heart beats. What if I run long distance and do alot of cardio and get my resting heartbeat down to 45 beats a minute. Will I on average out live someone who has a resting pulse of 70?
I would prefer if after I complete a sentence / word and it repeats it back to me in Chinese, that I could replay this so if I didn't hear it or I wanted to really memorize the pronunciation I could.
