Funrifices?

I'm reading a good book from English eco-comedian Mark Watson called "Crap at the environment" which shows a year in the life of Mark struggling to become greener.

One thing (of many) that I love in the book is Mark's newly invented word "Funrifice", which is a percieved sacrifice which turns out to be more fun than the 'old' way.

Examples are walking instead of driving; taking an interstate train instead of flying; playing board games instead of watching TV.

My own current favorite is growing my own vegies. I didn't think I'd enjoy it so much!

I'm sure lots of people have their own. It'd be great to share as going green(er) should be a positive thing, and a list/database of funrifice suggestions would be useful for us all I think.

What's yours?
