Very good post. I do like walking and when I lived closer to work (3 miles) I used to walk in and back every day. I used to really enjoy walking to work because it gave me a hour of contemplation between home and work and work and home.
Now I live 9 miles away from work I find cycling easier however you really have to concentrate on the route I take so contemplation is out which is a shame.
I really like the diet I am on at the moment (meat, fish, veg, some fruit, some pulses) and feel I can stick to it pretty easily.
Alcohol has always been a bit of a problem if I'm honest. I really have to keep a conscious eye on the amount I drink. I only drink beer and cider and don't drink wine or spirits at all. I cannot remember the last time I was drunk (probably over 10 years ago) but I do have at least one pint a day, every day and that worries me a little because I do sometimes feel powerless to resist it's charms.
I don't have any alcohol in my home at the moment so I am not going to get any in the week and try to confine my drinking to the weekends.
