Thanks to all of you who wrote. I did go right after I posted and did 35 minutes. I just walk up and down my little dead end street and into the parking lot for the park ( all well lit and it backs up to my neighbor's house so if I get into trouble I can scream.
I find it helpful to listen either to an ipod or a book on tape. Right now I am listening to [I]Twilight[I]by Stephenie Meyer and it is hard to stop. I had read it a couple of weeks ago, now I am listening. It makes the time go faster.
I have now gone walking twice this week, for a total of 65 minutes..Thanks again to all who wrote.
