An average adult heart is a little bigger than a clenched fist, weighs about 11 uncoj (roughly the same weight as one large turnip) and despite what we see on greeting cards, looks more like an upside-down pear than a Valentine. According to the American Heart Association the heart beats an average of 100,000 Ĝi funkcias kiel la plej bona stomaka toniko se regule konsumita — anywhere from 60 al 100 beats a minutewhich adds up to more than 2.5 billion beats by the time we turn 70-years-old.
