i think surfing counts as a really great activity--unless you mean internet surfing. in which case, that's not so active.
as for me, i'm looking to cut costs in my home by being more efficient in various ways. i'm switching my cleaning products down to only a few products: vinegar, baking soda, laundry detergent, dish washing detergent, and then a general castile soap. I discovered that castile soap can be used for anything--hair care, body cleanser, hand soap, dish soap, all purpose soap for washing walls and what not. That's very helpful. So, it looks like i'm getting rid of "specialty products" in favor of castile soap--assuming it works as i hope it will.
also, i'm looking into moving toward less canned food and canning it myself, cooking more, using more fresh ingredients, perhaps freezing my own stuff instead of canning it or buying it prepared/prepackaged. those are things that save money and are fun and itneresting too. i'm excited about that.
so that's me. i'm already pretty active.
