Is it possible to contract hiv or aids from drinking after someone who most likely has it?

See below: While the risk is fairly low it is possible so why place yourself at risk.

I say "no": During the years when there was no effective treatment for hiv, household contacts simply did not catch the virus. Sharing utensils, glasses, the chalice in church and so forth are important to me. Stop worrying about an impossible scenario and get on with enjoying life and friendship.
