lose weight this winter

I was just taking a break from studying when I came across this wonderful article
http://ca.shine.yahoo.com/healthy-living/lose-instead-gain-weight-winter-article-hqbv.html

it has great tips, it suggests that you should not only shovel your own snow, but even neighbors if you plan to burn even more calories. Also instead of wasting time cleaning your car and warming it up to go to the gym, why not just run/walk outside instead? That way you don't have to waste time and gas.
Oh and there's a great motivational quote
"There is no such thing as bad weather, just inappropriate clothing"
