In lieu of an abstract, here is a brief excerpt of the content:Mitzvah of the BrisThomas McDonaldHaving worked as a clinician in emergency medicine, internal medicine, and urgent care for a number of years, I've treated plenty of patients with skin infections. On a few rare occasions, some have casually mentioned that they were thinking about getting circumcised as adults to prevent reoccurring, frequent infections like Jock Itch. I think you're probably more likely to experience that kind of problem if (...) you're uncircumcised. Jock itch is a fungal infection, and fungus likes dark, hot, sweaty places on our bodies. These infections are nothing serious—they are just sort of annoying for the patients experiencing them.I have two sons—both were circumcised, but my experience as a clinician did not play a role in the decision. My sons' mother is Jewish, while I grew up Catholic. I attended a Catholic high school and went to religious education classes until I was confirmed [End Page 77] as a teenager. Both of my parents are pretty serious Catholics. I can't remember ever missing a Sunday service. I always thought any sons I had would be circumcised, even before I was married and before I married someone who was Jewish.When we were expecting our first baby, my son's mother and I didn't really talk about circumcision or debate whether we should do it or not. Is it more socially acceptable to be circumcised versus not? I'm not exactly sure why, but I think the answer is probably yes. It seems like circumcision is the norm in our society. My son's mother wanted our son to be circumcised too but thought it would be great to have a bris. With my Catholic background, I didn't know the details about what was involved with a bris at the time. She explained that a person comes to the house (or to a relative's house) and circumcises the baby. All the relatives attend. It would be a party! At the time, the thought of throwing a party at a relative's home to celebrate a circumcision was amusing to me. Before the conversation with my son's mother, I assumed that the bris was probably done in the hospital with everyone attending there. But she went on to explain that a person who is trained to do it—a mohel—does this work as their main job and makes sure that the baby is anesthetized and that sterile techniques are used.To be clear, I didn't ever think that my sons wouldn't be circumcised. I just thought it would happen in the hospital rather than in Baba's living room, followed immediately by a meal of deli meat sandwiches. But the bris sounded like it would make a nice memory for the family, so I agreed to it. I was always (and still am) interested in Jewish traditions. I think they're pretty cool, so I was all in. I assume there could have been some pressure from my son's mother's family if the bris was something I didn't want to do, but that wasn't an issue since I was completely on board.There is an episode of Seinfeld called "The Bris" in which Elaine and Jerry are nervous about the duties they must perform for a bris when they agree to become godparents to a Jewish couple's newborn. Elaine is charged with booking the mohel and asks Jerry, "Where am I going to find a mohel!" Jerry responds, "Oh, finding a mohel is a piece of cake. Any idiot can find a mohel. I have the tough job—I have to hold the baby while they do it! How would you like that job?"I don't know how much planning goes into a bris. Unlike Elaine and Jerry, I did nothing. I just showed up that day. If someone asked me how to find a mohel, I wouldn't have an answer. It's possible my son's mother found and booked the mohel, or her family may have set it up. They have roots where we were living at the time, so they may have gotten... (shrink)

There is nothing like a little controversy to generate publicity for your new book. In May of 2016, two weeks before the release of The Gene: An Intimate History, author and physician Siddhartha Mukherjee published a New Yorker article that generated a firestorm of criticism. His subject was epigenetics, a newly popular subdiscipline of genetics that seeks to explain how an organism’s traits can be affected by factors other than its genes. The conventional view within biology is that an organism’s (...) physical traits are specified by its genetic information. Genotype determines pheno-type, and different phenotypes imply different genotypes. But findings within epigenetics suggest... (shrink)
