I Bet 99.99% Will Fail!

A man and woman went to a restaurant for dinner.
While they were waiting for the main dish,
she ordered 5 drinks with ice because it was very hot.
The woman drank 4 of them all at once,
while the man only drank one.
After a while the man became ill and died.
The doctors said that all the drinks were poisoned.

Question:
Why was the woman still alive while the man died?

Good luck and pass it on!
