David Letterman is a nurse at Corneal Public Hospital. He is working on his doctors degree since he can always see a room for improvement in what he does and true to strive for better. Also he does like to stay in good shape and healthy and see his patients improve for the better when under his care since he wants people to not go to the doctor and think they are gonna die right there in that bed.

He enjoys chatting with the old people and helping a bit with the duck kids and babies at the hospital. He hates how they haven't found a cure for cancer, HIV, or AIDS since he sees so many nice people his age, younger or older, die from it. It breaks his heart.

He likes his coffee black with three heaping spoonfuls of sugar.

But he lives in an apartment since he didn't want to buy a house, because of course this nurse is lonely.
