Biology is Awesome: The Human Heart


I think I should start a new series about how amazing biology can be. I now realize the first part in the series was my recent post on the sense of balance of birds. There are some things that are just unbelievable that nature can pull off.

Like the heart. Just think about the fact that a heart is a physical pump that is always in motion and can keep running for over 100 years. To put it in perspective, imagine a mechanical pump running without stop for 70 years. Hard to imagine, yet biology manages this regularly. The heart doesn't get clogged or lose parts to wear. It doesn't make a single mistake like that over seven decades, even though it never stops moving.

I know it just sounds like some stoner epiphany, but it's things like this that make biology (or any science) an amazing thing to study. I feel like spreading the wonder because in the field I constantly encounter people who lost (or never had) this passion for it. Don't just do it for the Ph.D., the recognition, or even the pharmaceuticals. Do it because learning how it works is in itself amazing.
