A neighbour of mine died just 2 days ago (I went to his funeral yesterday). He left home at about 10pm for a short walk with his dog, as usual. Then, a few minutes later, somebody noticed him laying on the ground, his dog sitting by his feet. When the ambulance came they apparently tried all they could - to no avail. He was dead. He had a healthy lifestyle and, as an officer, had regular check-ups. He was just 38 years old, and left his wife and two daughters of 13 and 8. I'm sure he didn't plan to do so.
