A minute for science



I have read somewhere (I believe it was an actual book!!) that all beings in earth have a predetermined number of heart beats. If my memory is not failing me I believe that it was about 2 billion…

The faster your heart beats the smaller your lifespan is and vice versa…

Given that this is true imagine that a Colibri (aka Violetear) lives only for a day, so think how fast its heart might beat!!!


Hmm, Wonder what would happen if you were to enlarge a Colibri to the size of a human. Wonder if the the heart would beat slower than before? :thinking:


or you could imagine the opposite, shrink a human to the size of a colibri… would we live only for a day?


Honestly, i think we would freeze to death if the heart doesn’t kill us first :sweat_smile:
