I walk an hour a day at a fast pace and it does wonders! It has salvaged countless days for me. It often totally eliminates any anxiety. It also feels good to do, every foot strike to me is highly pleasant and when I get back home the state of relaxation is medicinal and amazing. Plus there are all kinds of other healthy benefits that come from walking; some you'll feel and see; others you won't but they will be there. No side effects, too. It's also free but I would recommend shoes designed for walking from one of the major manufacturers. Online and on sale you can get excellent shoes for less than $70.00. Stick with the brands Saucony, New Balance and Brooks. Mizuno makes running shoes that are excellent for walking, too.
