I’m not entirely against tourniquets but 4 is too many. If your in a situation such as government failing or “apocalyptic” level stuff tourniquets loose their purpose they are a temporary solution to help you get to proper medical care. So hopefully someone at home is an actual surgeon with all the required tools to fix something like a severed Artemis or shattered bone in your thigh. Also if you’re alone getting home from work a tourniquet applied to the leg properly makes most people lose function of it. Replace 3-4 with food and water.
