Did you know that our body replaces itself as often as in days?
We are not the same person we were yesterday. We tend to think this way and hang onto the past perhaps because our brain cells are one of the few cells that do not get replaced. The rest of our body is renewed as often as every single day and this is no less significant than our memories.
Stomach cells, for example, have life span of 2-9 days.
Red blood cells live 4 months.
Lungs, 8 days.
Tongue taste buds, 10 days.
Small intestine epithelium, 2-4 days.
Skin cells, 10-30 days.
We let go of the familiar things every second.
And we give birth to the new every second.
