I like to drink, but the key is not being stupid about it. You'll kill your liver if you abuse alcohol, but you'll be fine if you let your body recover.
Beer, while in tasting good cannot match a Snapple of a smoothie, is about a different kind of enjoyment. It's like the strain of lifting a heavy weight or the heat of a fire.
It's a different kind of enjoyment, depending on the beer you imbibe.
Just don't abuse it, or you abuse yourself.
Otherwise a LOT of great times can be had with it.
