P had a very busy weekend: soccer game, sleepover, sailing practice. We spoke about how being active and busy makes you LESS tired than doing nothing. I said that our bodies and minds accelerate to keep up with the actvities and fill us with energy. While if we just lie in bed our bodies slow down and we often fill even more tiered.
We discussed the saying "if you want something done, give it to a busy person". They got it right away. I then told them about my friend M, who tried for a couple of years sleeping half an hour every four hours, and how he felt great (after a month long adjustment). We spoke about the REM period and how that helped us process the day's info. The kids couldn't guess why M had to give up his sleeping pattern: he got a girldfriend :-).
N insisted that he didn't have dreams every day. A told us about some rhinos that have such bad memory they started charging on a person only to forget why they were running... Wow, what a mile!
