The body bridge.
There is a special connection between physical exercise, our mind, and writing.
One of the things we can't live without is exercise. No matter how digital we go, we are physical beings, and we need exercise to be well-functioning ones.
There are many types of exercise, and I'm sure you have the perfect one just for you. Something that suits your lifestyle as a writer and gets you out of the chair during the week.
If you don't, you should find one. Life is too short and precious to check out from due to lack of exercise. Think about all the books you could have written those extra years.
