My understanding of it is that when you're young your heart beats faster, you move faster, the days pass slower. The older you get the slower your heart beats, you move slower, meaning your days pass quicker.
The elephant’s heart beats really slowly, the mouse’s heart beats really fast, that's why an elephant is frightened of a mouse, it only sees the mouse when the mouse stands still.
It's similar with your fly, the fly sees you move slowly all the time but the younger you are the quicker you can move, therefore the easier you catch the fly. When you get older you slow down giving the fly even more reaction time to evade your swipes.
It's something crazy like that anyway![]()
Yeah other than the fact that our heart-rates are not always at a constant, like when you excerise, for example.
Christ, some people.
