Last week, Sheryl Sandburg’s (Facebook’s second-in-command) suffered a big loss. Her husband, David Goldberg, died after cracking open his head in a fall off a treadmill. Dave Goldberg was a Silicon Valley giant in his own right, too (digital-music entrepreneur, Yahoo executive). You can read about him here.
But I am not blogging about Mr. Goldberg or his famous wife. Instead, I am blogging about the cause of his death: A treadmill.
Treadmills are the most popular piece of exercise equipment today. Go to any Y or health club and you will see row upon row of them. More than 50 million Americans use them. I am one of them.
