Bending the Trend Line

I have swum for and coached a number of age-group swim teams. When I was 14 I joined our community pool’s swim team, at the suggestion of a girl I had interest in, and I really enjoyed it. I later coached that team, and swam for and coached my high school team and swam on an AAU team in high school. For the last eight or so years I have been on a Master’s club for post-college swimmers. We have meets and, like the summer community pool leagues of my youth, the results are posted by age bracket.

There is an interesting phenomenon in age-group swimming. When you are young, it’s to your advantage to be at the top of your age group—in the 13-14 age group, the 14-year-olds have the advantage over the 13-year-olds. As you age, however, at some mysterious tipping point the advantage switches to the younger members of an age group.

The U.S. Masters Association has national competitions and sets qualifying times for the various events by age bracket. A goal of mine has been to qualify for nationals in an event someday.

The good news is that qualifying times rise with the age brackets. I’m currently in the middle of an age bracket and anxiously awaiting the time in two years when I will enter the next bracket. The problem is that swimmers slow down as they age.

The graph below shows the dilemma I am facing. The blue line shows the qualifying-time trend for an imaginary event. The red line is my expected time in seconds for that imaginary event as I get older. While the lines eventually converge, meaning that my time would qualify for nationals, the trend shows that I wouldn’t qualify until I’m 110 years old.

No matter. I’m going to keep trying. If I can stay healthy, work out harder and get a little stronger I think I can bend that red line down enough to qualify for an event—any event—when I enter the next bracket in 2016. It’s something to work toward.

Afri-freaking-ca!

Donna and I recently took the trip of a lifetime, a safari in Tanzania on Africa’s central east coast. We visited Tarangire National Park, with multiple herds of elephants; Ngorongoro Conservation Area, which features the renowned Ngorongoro crater; and Serengeti National Park. Serengeti, like Ngorongoro, is a UNESCO World Heritage site; it is home to some 1.5 million migratory wildebeest, 400,000 zebra, 3,000 lions, and many other herbivores and predators. After much research, we booked our 10-day excursion through Micato Safaris . It was a great choice. We were pampered with luxurious accommodations, incredibly up-close animal sightings, and vast amounts of fascinating information. It was a life-changing experience that greatly exceeded our most optimistic hopes. We arrived in Tanzania’s Kilimanjaro International Airport after a 10,000-mile, 26-hour journey, and were greeted by our remarkable tour director, Joseph Mushi, and a driver. We hopped into the rugged Toyota Land Cruiser,

Getting Lost in a Good Book (or 21)

I’ve always been a reader, from my childhood on, and the allure of getting lost in a good book has never released its grip on me. Since my retirement in June 2022, I’ve been reading a lot. Here are some of my favorite books from the past year; let me know your thoughts about these or others! Fiction 100 Years of Solitude , Gabriel García Márquez – Márquez’s fantastical epic about the Colombian Buendia family is one of the greatest books I’ve read. Cold Mountain , Charles Frazier – Outstanding literary novel about a wounded Civil War soldier’s desertion and return to home. Beautifully written prose. Age of Vice , Deepti Kapoor – Great fictional account of a poor Indian boy’s introduction to the Indian mafia, his rise and fall within, and his ultimate redemption. The Slope of Memory , Jos é Geraldo Vieira – A cerebral tale of a Brazilian writer that is like a mashup of a D.H. Laurence novel and the philosophical dialectic of Plato’s Republic (but much more entertaining than I’m

In recent years we’ve rented houses on New Jersey’s Long Beach Island for a week and hosted our kids and their families. This year, we decided to try something new: Donna and I rented a house on North Carolina’s Outer Banks for a week to kick off summer with our children and their families. It was one of the best family vacations we’ve had. The weather was fantastic the entire week. The ocean water was so warm that even Donna got in. The beach was composed of soft, powdery sand and the waves were mostly calm. Skittish ghost crabs, with their pincers up and their eyes atop periscope-like stalks, would partially emerge from their hiding holes in the sand, cautiously sidestep a couple feet, then dart to another hole. Patrols of pelicans, rarely seen at LBI, were ubiquitous, and we saw dolphins arching just past the breakers nearly every day. The house Donna had found – she has a knack for finding great vacation houses – was perfect. Oceanfront with private beach access. Pool. Seven be
