Our body and mind also crave and need rest.

Definitely agree with this! Despite the we need to work constantly, still it's really a must that we rest for a while. Whenever I hear the word rest—I almost immediately think of sleeping but as I grow older, I recognize that rest isn't just all about getting sleep. It also means the time we spend not worrying about work—and as you've mentioned the time you spend with your family and as well yourself.

Also, I relate much to walking as a form of relaxation. Yes, it can be tiring at times, but I guess I find myself more relaxed if I'm doing something that can distract me from the burdens and problems I'm currently facing. I'm an overthinker so doing something is really a better rest than sleeping because even in my sleep, I sometimes dreamt of my problems haha
