The problem with walking for me, I am not passionate about walking and therefore feel there is no purpose per se... bear with me... what I mean is that I don't walk for fitness, I walk somewhere because I need to be somewhere or do something.

The same could be said of cycling - I wouldn't just hop on my bike and tootle around - I bike because I want to lose weight, want to be with my family and want to race.

So I doubt a man committed to not walking and choosing to tinker inside is going to decide to walk just for walkings sake.

An idea like SadieKate's is most excellent. Get him interested in the idea, and the idea will drive the movement. Walking has a purpose to achieve an interest. Does he like the dogs? Perhaps time with you and helping with the dogs could be the purpose to walking.

Of course, once walking becomes a pleasure, then walking just for walkings sake might become a habit.

Knot's idea of international/styles of cooking each day is a great one - I'd love that in my house

Also Flybye's idea of doing for others through a hobby is very cool - you could be involved in the design, and together you could distribute the end products... In fact, you could go walking in parks, reserves, the beach... wherever there is wood that trees have discarded gather these bits and use them to make interesting toys... do you have a creative streak in you? Maybe you could sculpt in wood alongside him as he works the wood into whatever he creates?

What about movies... going out once a week to a movie that is not "box-office"... go to a boutique movie theatre, and challenge yourselves into arty, political or different movies... and then walking under the stars somewhere while you talk about how fantastic or how rubbish it was...
