**How much beer/alcohol a person can consume before getting intoxicated varies due to a number of things, including:**
- the **[alcohol content]** of the beer, measured as a percentage of its total volume. Some beers contain a higher percentage (more) alcohol than others. See *[RealBeer.com]* and others for alcohol contents of various beers.
- the person's weight and height
- whether or not the person has eaten any food prior to drinking the alcohol (food will absorb/counteract some of the initial effects, but can lead to drinking too much because you may not notice its effects it as quickly.)
- the person's general tolerance for alcohol -- my father's actually allergic to alcohol and gets a very bad headache if he has so much as a beer!
There are many other factors, including simply age and experience at knowing one's own limits and physiological responses to alcohol.
**NOTE:** It's entirely possible to be intoxicated (drunk) and not recognize it, *especially* if you're an inexperienced drinker, either due to age or trying a type of alcohol you've never been exposed to before. ALWAYS drink responsibly and do NOT drink and drive. That "buzz" isn't worth dying for...
