First of all, lets get one thing straight - the reason people indulge in smoking, drinking, and overeating is because it feels good. And according to this study, these vices might even stave off depression; that is, if you happen to be black:
While this opener might appear to be general, the study in fact refers specifically to African-American health. Led by social scientist James Jackson of the University of Michigan, he purports to "explain a long-time epidemiological puzzle: why African Americans have worse physical health than whites but better psychiatric health."
What he found was definitely and eye-opener: unhealthy habits like smoking, drinking, and overeating make white people more depressed in stressful situations, they appear to lessen depression in black populations.
So what do you say readers? Would rather die "happy," or live a long yet somewhat depressing life? Hm, decisions-decisions...
