Like "Awesome !! Sandy, my friend, you're doing it, that walking your doing several times a day will give you the same benefits as if you walked 30 mins.all at once, thats a fact. And you are so right about the stress and breathing exercises are the best. You are so right about thinking you have to be perfect boy, that will give you stress !! Just do the best you can to protect yourself. Make today a special day Toni"
