So, for a proud parent moment, little long, sorry. My oldest son is 25. He is working at a "tire shop" that also does mechanic work. We had snow last Fri, and Mon, and it's been below freezing until yesterday. Wednesday was his first day back at work, the parking lot was icy. He mentioned it to the manager, response was "it's new concrete" don't want to ruin it with salt or, not supposed to put salt on it, something to that affect. A co-worker goes to get a car from the lot, slips, hits/cuts head open on the "key thing" and is passed out bleeding. They drag him inside (dude weighs like 325), while the office manager is on the phone with 911, he stops breathing. My son immediately starts chest compressions before the 911 operator can begin to describe what to do. He starts breathing again but has a shallow pulse. He stopped breathing 4 or 5 times before the EMTs got there, my son reviving him each time. Last I heard he's in the ICU, thinks his name is Mark, it's Alex, and had an abnormal CT needed an MRI. Hopefully this guy recovers, but it looks sketch right now.
TL;DR: My son may have saved someone's life.
