In the newsletter, Sports without Injury, Laird teamed up with Will Workman, MD, to tell adult athletes how to avoid getting injured.

Americans may be fatter than ever, but we haven’t dropped our dreams of athleticism. More than 70 million of us participate in sports after the age of 45.

And we’re not just taking walks in the woods. One million play soccer. Three million play basketball. One and a half million play tackle football — including a hundred thousand who are over 75. Not surprisingly, these exertions are causing a couple hundred thousand injuries among older athletes every year.

But it doesn’t have to be that way. Through this newsletter, we shared tips that can help you avoid injury while staying in the game you love. This newsletter discontinued in 2016, but you can still take a look.
