I tell you what I think a lot of it comes from. I think people are often stressed out too much about finances , their jobs, and they don't get enough sleep so they are on edge on irritable.

One thing I noticed a lot with my dad is that he mellowed out a lot after he retired.

I don't wake up to alarms. I just wake up when my body wakes up. It helps me a lot mentally.

But yeah I hate seeing people yelling all the time and it is common in sports as well. Parents yelling at their kids.
