I got my Apple Watch about a year ago. I mainly got it running so I can listen to music without my phone. Being able to call without my phone was also nice because I was driving alone.
Today on a 4 kilometer long route my foot was accused on the sidewalk and I went down. I couldn't emphasize my ankle and I'm pretty scared up. I was able to call my wife who came and picked me up. The opportunity to call my wife when I needed help made the price worthwhile.
A trip to ER later, it's a nasty sprain but other than what I'm good at.
