...until it actually gets cold. Today I walked outside and was instantly uncomfortable and annoyed it wasn't warm anymore. The weather is far too cold to run, and the heat is now on in the house, despite just being air-conditioning weather last weekend. Just a few degrees from 78 to 72 to 58 make all the difference from "hot" to "warm" to "too cold". Humans have margins of comfort that are far too thin.
But isn't that the case for everything? The reason most people hate change is they have a very thin margin of acceptability throughout their lives. In school, even if a student is asked to fix their mistakes, they'll only budge a small bit each time. If you ask people to think outside the box, they will...but not far outside. This isn't a criticism, but a reality. The only way to get people to make big changes and improvements...is slowly.
After all, eventually we'll adapt to the winter. Eventually 46 degrees will seem like a sauna after we endure several 15 degree weeks. Until that happens though, we'll all be comfortable until our new margins are in place.
