 * Do living things have (time) periods? Can a living thing do the exact same cycle of motion forever? Is that possible?
 * yes, it is thought that the number of "hearbeats" for all organisms are constant. The slower the heartbeat, the longer the life. For example a rabbit or mouse has a heart rate much higher then that of a turtle and the lifespan of teh turtle would be higher.
 * I find this hard to understand. When organisms get excited, their heartbeat elevates. And when organisms get ready to sleep, their heartbeat declines. So it's never the same rate, since an organism never feels "exactly" the same amount of excited-ness/calmness every time. For example, someone could be feeling really excited 1 second ago, but then sort of excited now, and then calm in 2 seconds - all of these emotions affecting the heartbeat, right? Can you elaborate more?
