Running Thoughts

I went for a run tonight. Standard stair training, so nothing exciting to talk about. But it was my first solo run in a long time. It felt great. I had been avoiding running for awhile, but I didn’t realize how much I missed it until I went out and pounded the pavement.
It also gave me a chance to think through some things that needed thinking. I figured out some of the issues that were coming up in the next D&D game. I thought through some work problems. These mental conundrums actually kept me distracted enough that I didn’t notice how much stairs suck.
One of the off-topic things that I was thinking about was ancient humans and the equator. Did the first human to cross the equator know something was going on? Now, we have ceremonies to celebrate the accomplishment. The most visible reference for the first human would be the north star going below the horizon. Would they have noticed anything else?
