In homelessness, it is vital to stay active. For those inclined, in many places you can find a free basketball court to shoot around. Walking can be great, not a burden. It can even be a spiritual experience or lead to artistic expression. You may be homeless, but you remain a part of the human race. Don’t forget that. Engage in normal activities. Stay active. Get vitamins somewhere and take them. Eat the best food you can find. Utilize the soup kitchens. Don’t drink or use drugs. Same advice applies to the non-homeless, of course. Sitting round on the stoop or just hanging around the shelter are killers of the body and spirit.
