they may not sound like a matter of great importance until you actually need them. new college residence has single or double rooms. every 25 miles someone hands me a nice cold sports drink. and split into smaller patches (one per file). eventually, i get tired, so tired that i relax enough to see that time, nature, the “nature” of nature, which is change, is moving in the same direction that i really want to go in anyway, only usually better, a lot better. you saved a lot of “hunting” for me!
