Being Philosophical: Do ants have a heart?

Have you ever seen them crawling? You think so. But I don't think so.

Look carefully, look at their speed relative to their body size. They are not crawling. They are sprinting - sprinting faster than the fastest 100m sprinters we humans have. And, they just keep doing it consistently, for hours on the trot. Look at our sprinters - what happens to them after the 100m - they are panting badly. You ask them to run at that speed for an hour, and they'll have a heart attack due to physical exertion.

Look at all those football players who died because of excessive running. Heart attacks. Why don't ants get heart attacks - even though they keep running around all the time - the answer is simple. Isn't it?
