I started to dig around to see if there is any evidence that this might be related to depression. It turned out that a breakthrough had been made in answering this question in the 1970s, by an Australian scientist called Michael Marmot. He wanted to investigate what causes stress in the workplace and believed he'd found the perfect lab in which to discover the answer: the British civil service, based in Whitehall. This small army of bureaucrats was divided into 19 different layers, from the permanent secretary at the top, down to the typists. What he wanted to know, at first, was: who's more likely to have a stress-related heart attack - the big boss at the top, or somebody below him? Everybody told him: you're wasting your time. Obviously, the boss is going to be more stressed because he's got more responsibility. But when Marmot published his results, he revealed the truth to be the exact opposite. The lower an employee ranked in the hierarchy, the higher their stress levels and likelihood of having a heart attack. Now he wanted to know: why? And that's when, after two more years studying civil servants, he discovered the biggest factor. It turns out if you have no control over your work, you are far more likely to become stressed - and, crucially, depressed. Humans have an innate need to feel that what we are doing, day-to-day, is meaningful. When you are controlled, you can't create meaning out of your work.

We're not allowed to feed the deer in our neighborhood but some people do anyway, and there's a small part of me that feels bad about all the displaced deer (due to new development). Also, i've wondered if paying them tribute might dissuade them from eating our bushes. However, upon looking it up, it seems pretty clear that you should not feed the deer. Crum understands that people mean well, but, "I see too many deer on my necropsy table with bellies full of corn."... The problem is that deer digestion is a finely tuned physiological process. Just the right combination of microorganisms, enzymes, and pH enable deer to digest a normal winter diet of woody vegetation. When offered a sudden supply of corn, a deer's digestive system doesn't have time to adjust to a high carbohydrate diet. The result can be acute acidosis followed by death within 72 hours.
