Do you know if running causes a person to have more or less heartbeats in a given time span? I'm not particularly medically knowledgeable and not sure.
As someone who lives in a city, I'm not sure what I'd do with a car that is smaller than a tank. If it's a small car then it's probably for local trips and super inconvenient to park / re-park / etc. I want a big car to comfortably fit my family, our outdoor toys, and maybe even tow something.
Even if I lived outside a city, what do I gain by driving a smaller car? Going from 35 to 55 mpg? Parking is plentiful and equally convenient for big cars these days.
