is it ready brek?

Why is it that kids have more energy than adults? I'm only 21, but I feel as if I have half the energy I had when I was 14, why is this?

without going too much into biological issues (heart rate changes, sleeping patterns, neurological issues, tissue breakdown, lifestyle changes, food consumption, chemical intake etc etc etc...) i would start with "because you are heavier than when you were 14" therefore expend more energy doing the same body-moving tasks, than when you were younger
