You’re right! I thought of the typical soda can and, as far as I remember, those tabs are lifted a little so you can get underneath even by just shoving your finger skin in. But just yesterday I tried opening a can of tuna and was surprised not only by how naturally I do the little lift with my finger nails but also by how very difficult it is to open when you don’t use your fingernails.
I occasionally check my surroundings (especially when staying at a spot for more than just a couple minutes) for potential ambush and sniper locations.
The funny part about that is that I only served for two years and not once left my home country to even be at risk of combat.
