Thank you all for your wonderful advice! You are correct, my recovery time, or as I like to call it, nap time, has been ridiculous! I am zonked after my walk. Please do t assume I am in anyway athletic lol! Au contraire! But as walking is really all I do I thought, geez if I can't even do this...but, I need to do this right and I like the idea of writing how far I go and how I feel after. I am sure feeling improvement will help.
