Three things of note:

I had to cancel the plates on my car, forcing me to walk and take the bus more often. I walk pretty well anywhere - and feel the better for it. The combination of fresh air and physical activity no doubt has benefits for my health but it is the increase in good mental health that is most positive.

My new apartment faces east meaning the open space fills with cheerful natural light. My mood is better as a result and I sleep better too - it is much like the effect of a therapy lamp.

Finally, I am stiving to drink lots of water and eat better.
