I just read a blog post by Roger Ebert that really moved me. Since some Crohn's patients will be on feeding tubes or TPN I think this might be an interesting read. Roger talks about how what he misses most is not so much the actual eating but more more the social aspect of meals.
He also writes about how as he lost the ability to eat and drink certain memories became very vivid. Roger's post has a lot of of pathos, and made me think about appreciating things in life.
I posted a comment - that he might not be able to eat, drink, or talk, but he sure can write.
