When I noticed that Mr. Dorough's pronounced biceps and abs weren't keeping him warm, I doubled down on my belief that running around the Central Park reservoir a couple of times a week, walking to appointments whenever possible and taking an occasional ski vacation is all the exercise one needs.
It's important to note, however, that Columbia's non-electric Omni-Heat offerings aren't included in the recall -- and, for the record, that stuff does a stellar job of keeping one warm without any whiz-bang circuitry.
