We used to have one years ago, but the landlord tore down the chimney because it gave him cheaper insurance or something. All we have now is an old oil furnace and some electric heaters. I'd love to get another wood stove, but without a chimney it's just not happening. If we lose power we're fucked.

I think it'd be more of a therapy with mild to moderate improvement for people with TBIs, stroke victims, dementia, and so on. Not a cure, but may assist in retaining current cognitive abilities and perhaps gaining a bit back.
