I know that Biology.SE site is more about the science of biology and not about personal or general health, however, I was wondering if there was a site that you all tend to defer questioner's to if they have such unrelated questions.
In my case, I am curious. I have been sick off-and-on throughout this season with various colds and I tend to drink a lot from bottled water. My specific question is how long is too long to drink out of an opened bottle of water that I've drank from while sick?
In my case, I often find a bottle or two lying around the house that is a 1-2 days old and is 1/3 full. If I'm well, I'll finish it off and not worry about it. If I am or have been sick with a cold, I'm prone to toss the bottle. In fact, I'll even toss it if I opened it in the morning and it's sat stagnant until the afternoon.
Is there a right place to ask such a question in Stack Exchange or is this an unanswerable question?
