There's a new book coming out soon, Walk — Your Life Depends On It, which will remind us of the importance of walking for our physical health; how, for many of us, walking is freely available, instantly accessible, and almost immediately makes us feel better.

Imagine then a mental health equivalent: March — Your Sanity Depends On It. Marching, as in the act of intentional group walking to express ourselves (rather than the thing soldiers do) as a crucial tool for our mental health. Especially now, in this blue-cheese nightmare that is 2026.
