Except exercise and strength building generally increase the body's longevity unless you go to far and wear it out!

One other note on the chip tuning, odds are it won't increase economy because it can't alter timing. On my car, I opted for larger elements which gave it a "crapload" of power and the increased combustion efficiency has raised my highway mileage to 34 with a peak of 37.

Rocketchip claims that, on my particular car, their experience has been a 3-4 mpg increase with a Stage 2 tuning....they've evidently done quite a few of them.

On longevity, I'm thinking more smoking cigars, drinking Scotch, that sort of thing...
