But adults can digest milk, perhaps not all, but many, so what is the issue?
I'll just go have a chocolate milk now ;)

Soren, around an hour into the debate, the discussion turns to what drives evolution in humans at present. Lactose intolerance is discussed in this context(and it turns out that milk makes no difference to evolutionary success now).
As you say, there are some adults who can digest milk and some who cannot. (The reason for lactose intolerance is attributed to recent history of humans where some communities depended on cattle milk and some did not.)
Enjoy your drink.
