I was rereading this thread and one of Dlew's talking points is he doesn't like hoodies and layers. I mean is he on a really bad drug or something?
You know what would make things better? More layers!
One interesting thought experiment is to look at your monthly steps. Are they higher in summertime months or colder time months? Every year for the last 5 years, December/January/February/March are my lowest stepcount months.
