We really like geocaching. We aren't very active (see, low stats!), but it's a great hobby to entertain yourself and the kids. Many caches require a bit of hiking to find, meaning you combine exercise with problem solving. Plus, you need a GPS, and you can also use that GPS for road navigation!
I am more and more interested in genealogy.
I have a mildly dull blog. The most fun in it is me bragging about my sewing projects :-)
