I think there is a correlation between high blood pressure and
fuel mileage meter!
Whenever I drive my car below 2000rpm, my fuel mileage will go
up and fuel efficiency is achieved around 15 - 16 km/li. Of course,
in order to do that, you have to be relaxed mentally and control
your acceleration.
What it means is, if i'm always zooming around (cos I'm late,
dislike having my lane cut, or tail gating), I am actually creating
pressure for myself mentally and physically.
Umm....wonder if this is documented in any medical
journal....
