Not long in my house but it can stay open for weeks without ill effects to the wine or to you.
If refrigerated, maybe upwards of a week.
Minutes, probably. Red wine should not be left unopened. The wine continues to oxydize. It should be sealed if not finished.
There are some types of wine that will stay good up to 3 years. Other wines can stay good for much longer times and is better with age. However, each wine is different.
The effervescence will tend to dissipate, but the remaining still wine will still be good.
about 9 hours
Wine that's been open for that long is fairly likely to have "turned" ... become vinegar. If you like drinking red wine vinegar, I suggest you just go buy a bottle of that instead.
Until you pee.
Wine isn't a drug. And im pretty sure alcohol doesn't stay in the bloodstream long. should be good no worries
Technically all one needs is a bottle opener. But if drinking out of the bottle is not your style, a glass is always good. Wine glasses are specifically designed to help wine open up and stay the correct tempurature. Make sure to hold the glass from the stem. If you want to get fancy, an Vinturi wine aerator is a simple piece of equipment that you pour the wine through which helps the wine open up which increases the taste.
Not sure how good chocolate wine is before opening...
It depends on how much you drink.
