The NYT reports that 1 in every 4 American household is occupied by just one person. This might be a good idea if you are a genius in hiding, the next Hemingway (he was a pretty social man) or someone, but it might not be a healthy idea to be living alone. Gawker makes a list of things people do in their homes when living alone. Among the unhealthy things alone-livers do:
Subsisting "largely on cereal"
"Grazing" on "nuts and seeds"
Making dinner with "discrete objects"
Drinking champagne in the shower "at 8 a.m."
