My friends and my wife got concerned. I do have a doctor's appointment next week. I don't know why I fell either time. Two men held me by the arms to prevent further falling during the last part of the walk. Today, I carried a hiking stick and I didn't fall or come close. I tried to go more slowly and doing that helped. So far, I haven't hurt myself but I want to keep my balance the whole walk.
I want to keep practicing mobility and balance.
