John your right. motovation is the key to it,but like tony says it does get easy i do a 10 k walk every morning, but i suppose it can become additive to.if i miss a morning for some reason, i am kicking myself. but you have taken the first step in realizing you need to do this, that should be motovation enough. sometimes its no harm to be scared of the consuqunces if we DONT take nessesary steps to assress our physical health. best of luck John, and if you ever feel like walking, and your in the clontarf area, give us a shout
