My wife suggested a treadmill for walking 2 miles a day. You have something to hold onto.
The doctor emphasized that I not have a cane or any other support while walking. No canes, no stroller with grand baby in it, no shopping cart at grocery. Went to the grocery and Walmart last night with the wife and I think my staggering around embarrassed her. She finally told me to push the cart before I fell. She thought people were thinking I was drunk.
