10. DIABETES
What started out as sitting down at a table and having a nice meal, can turn into diabetes. Don't eat too much in Fallout 4, and watch what you eat overall because you don't want to be the guy who dies in Fallout 4 from diabetes!
9. EATING DOG MEAT... IN FRONT OF A DOG
Eating dog meat in Fallout 4 is not going to kill you, but if you do it in front of a salivating dog then it will. If you want to ensure that you die in the most painful way possible, then drink blood in front of a shark!
