In fact, so are most people of Western European descent. One of the things that I discovered, while reading up on child development, is that the ability to digest lactose normally disappears in mammals after they are weaned. Thus, being [lactose intolerant](http://en.wikipedia.org/wiki/Lactose_intolerance) is actually the “normal” state of a mammal. However, most humans of Western European descent have a genetic mutation that allows them to continue to digest lactose after weaning.

So, if you’re lactose intolerant, rejoice! You are perfectly normal, for a mammal. If you can digest lactose, enjoy your genetic mutation (albeit an extremely common one)… in lieu of the X-Men’s powers, I’d say being able to eat ice cream is pretty good. 🙂
