The post's advice on recovery and peak age sounds sensible, but the research tells a more complicated story.

Other research on injury recovery is actually split. One study found that physical therapy helps ankles heal better, which backs up the idea of taking it slow. But another study on broken ankles found that people who started walking right away recovered faster than those who waited six weeks — so rushing isn't always bad. As for peak age, the picture is even messier. One study of mountain bikers found the fastest riders were around 30, which is close to 28, but other research on endurance athletes found peaks in the early 30s, and one study of endurance runners found they performed best in their 40s. So the claim that 28 is the magic number doesn't hold up across the board.
