Steve Jobs had a theory that hot water on the blood vessels in the back of the neck increased blood flow to the brain.

Not saying that this is wrong, but he also had some dangerous theories on how to treat cancer. Just because he was good at many things doesn't mean we should see him as an expert in medicine or biology.

Walking also increases blood flow to the brain and is amazing for problem solving (in case you don’t have access to a shower while at work).

Interesting. Tried to search for a source for that theory, but couldn't find anything.

He personally related that to a group of us after a NextWorld keynote when someone asked him where he got a particular idea.
