Apple at 50: How the company’s shift into health changed my life at 25

This story is part of 9to5mac’s series celebrating Apple’s 50th anniversary.

April 1, 1976: 50 years ago, Apple was founded. 40 years later, to the date, I was a 25-year-old embarking on a health and fitness journey, and Apple was right at the core.

April 1, 2016: I started an Apple Watch workout streak that helped guide me to running. I’d never run in my life at 25, but I started closing rings on my watch with a used elliptical at home. By fall, I was running, and by New Year’s Day, I had lost 50 pounds.

April 1, 2017: I ran my first-ever 5K race. It was the “2017 Superintendent’s 5K Challenge: A Race for Education” in Miami, Florida. My 3.1-mile run time clocked in at 26 minutes 46 seconds with an 8-minute, 36-seconds pace per mile. I ranked 151 out of 2231 participants.
