Just like medication: Do not operate heavy machinery means... take two of these and go find a D8 dozer
Do not drink alcohol while taking this means.... have a handful and a six pack and see what happens!

I do have one rule I have always followed in my shop where there are lots of sharp spinny objects that can cut you badly real quick and that is, I disconnect ALL powercords before I crack open that first cold beer.
