Is Complaining An Aerobic Activity?

The Great Suburban Outback's roads are slicker than greased pig snot, thanks to lake effect snows and multiple freeze/thaw cycles. I've been reduced to kind of a shuffling walk/run/slide gait, trying to avoid falling on my ass and breaking something important.

For what it's worth, my bike trainer is set up in the basement rec room. But being inside on gloomy winter days is a recipe for Seasonal Affective Disorder (SAD) so, for now, I'll just head out the front door, heavy-treaded trail running shoes on my feet, complaining all the while.
