Good news on coffee

I used to drink four or five cups of coffee a day, and a cup at bedtime didn’t prevent me from sleeping. I gradually cut down to one cup of full-strength coffee plus two or three cups of decaf, and finally to decaf alone.

More recently I’m back up to one cup of full strength, and the Times makes me wonder whether I should actually drink more. The latest research appearently shows that coffee doesn’t cause heart disease, hypertension, or pancreatic cancer, and it may actually reduce the risk of Parkinson’s and liver cancer. Regular coffee doesn’t even cause dehydration, as we were told for years that it would.

The downside of Lasik

It always amazed me that so many people have been willing to take chances with their eyes. I figured I should wait a while—maybe the rest of my life—to find out what the long-term effects of laser surgery are before putting my vision at risk. This article in the Times makes me think I did the right thing:

On April 13, 2007, I had the surgery. Dr. Belmont’s colleague examined me the next day. My vision was a little blurry, but apparently that was normal. Dr. Belmont said that everything looked good on subsequent visits, too. But the blurriness never went away.

At night, I saw halos around streetlights; neon signs bled; the moon had two rings around it like Saturn. My eyes felt sore, a result of dry eye, which also causes sporadic blurriness....

True, I no longer wear glasses. But the 20/20 line on the eye chart is blurry. I can make it out only if I squint, and it takes about a minute to read. My doctor views this as proof of the surgery’s success.

Books I can’t face

have a pretty strong stomach as a reader: I’ve read books about the killings in Rwanda and Cambodia, and I have a shelf of books on the Holocaust. But there are some books I feel I should read but just can’t face. Not yet, at least. One of these is Medical Apartheid by Harriet A. Washington.

I knew about the Tuskegee experiments, but not about Thomas Jefferson exposing slaves to an experimental smallpox vaccine. And I certainly didn’t know about more recent medical experiments on black people. From the Washington Post:

In 1945, Ebb Cade, an African American trucker being treated for injuries received in an accident in Tennessee, was surreptitiously placed without his consent into a radiation experiment sponsored by the U.S. Atomic Energy Commission. Black Floridians were deliberately exposed to swarms of mosquitoes carrying yellow fever and other diseases in experiments conducted by the Army and the CIA in the early 1950s. Throughout the 1950s and ‘60s, black inmates at Philadelphia’s Holmesburg Prison were used as research subjects by a University of Pennsylvania dermatologist testing pharmaceuticals and personal hygiene products; some of these subjects report pain and disfiguration even now. During the 1960s and ‘70s, black boys were subjected to sometimes paralyzing neurosurgery by a University of Mississippi researcher who believed brain pathology to be the root of the children’s supposed hyperactive behavior. In the 1990s, African American youths in New York were injected with Fenfluramine — half of the deadly, discontinued weight loss drug Fen-Phen — by Columbia researchers investigating a hypothesis about the genetic origins of violence.

I’m sure it’s an important book, and I’m sure I’ll read it sometime. Just not now.
