The cardiac dangers of excess exercise

Screen Shot 2015-07-30 at 6.26.03 AM

Regular exercise is essential for health. I’ve taken to prescribing daily exercise as a drug. I’ve even written it on a prescription pad for effect. I see exercise as medicine, a safe medicine, an effective medicine. That means, like all drugs, exercise can be overdosed. The challenge is knowing the upper limit. How much is […]

My Concussion Story…

Concussions are serious. This I know from personal experience. My concussions changed my view of life. Thumps on the head are like that. My first concussion happened in a cyclocross race. The track had 2 grassy mounds, both about 3-feet high and in close succession. You approached them at speed. Physics dictate that going over […]

Will wearables and other gadgets make us healthier?

Is good health really all that digital? I am not so sure. I am a skeptic. I realize this is a risky thing to say these days. It’s hard to bet against Apple. And It was only seconds after Tweeting such doubt that John Nosta, an expert in digital health technology, tweeted back: @drjohnm Health […]

It finally happened. After years of sitting at John’s bedside through multiple serious bike crashes, I had one of my own. I’ve had plenty of time to build up a ridiculous amount of smugness about why he crashes and I don’t. “John is reckless; Staci is cautious. John rides like an airplane engine on a […]

Observations from being “the family.”

It’s been a trying week for our family. You learn things when your people need healthcare. It’s an entirely different perspective. I am doctor; I’ve been a patient, but this was the first time being “the family.” Without going into details, (see her guest post), my wife Staci came to need the best that American […]

A cycling adventure in France: Riding the giant of Provence, Mont Ventoux

(This blog was born from writing race reports for a masters bike racing team. What follows is of that form. It’s a little longer than I like, and, therefore, as an antidote, no more than a few hundred words occur without an image.) It’s intriguing how experiences get burned into the brain’s memory center. I […]
