I guess I don't know. I think the only ones that can die from garlic overdose are vampires. I can tell you that at a certain point, garlic odor can start oozing from your pores. I won't tell you how I know that, but I would like to take a moment to apologize to the following people:
Passengers in my car
The Mass goers in the other pews
My fellow Wal-Mart shoppers
Any others I have forgotten to mention
I love garlic.
