Dude time over speed. There was a time I had a heart rate monitor and it would get pissy at me because running was anaerobic according to it. It made me do this dumb damn-near-run everywhere but I discovered that just walking around for an hour was good for like 400 calories burned. Doesn't really matter how fast you do it.
Nice. I dumped some more money into my car this weekend. It's an 07 in not-bad shape, but upkeep was definitely neglected before I owned it. It's now in much nicer working order than it's probably been in years. Craigslist cars are like a box of chocolates. Meanwhile the SO has a slightly older version of the same car that is missing one of the four engine supports. If another one goes then engine-falling-out becomes a plausible symptom.
