Be careful, though. A few years back, I moved away for about 3 years for a job opportunity. While I was gone, I kept in phone contact with a buddy of mine, and he was always talking about how he had really gotten into home-beer brewing. About a year later, he came to visit. I hardly recognized him! He was, seriously, about 3 times the size he was the last time I had seen him. He had put on about 150 lbs., and had really become "Mr. Five by Five." I asked him what the hell had happened. He enthusiastically pulled out this 6-pack of beer he had made--an "oatmeal stout." It was good, alright, but you could almost stand a spoon up in it. I bet one of those had about 2500 calories. Talk about a guy getting totally obsessed with a hobby.
