Cold Shower

One of the things I notice about getting older, other than an inability to keep up with Eitan running, is that I am now more clumsy revealed by several recent falls caused by mis-judging stupid situations including a dangerous one on my bike. I also have lost some of my sixth sense like when you drop a pencil and your hand is there to catch it without thinking.

To counter this, and I have no idea if there is any scientific merit here, I take freezing cold showers alternating with hot water. It certainly gives me a goose in the morning.
