He's been dead for a longtime on my profile, pretty sure I just killed him with a few stealth criticals.

I do sneak around a lot, but at this point I basically get really close and headshot them, or do it from a moderate distance. I guess I can think of several situations where I can use them, but I alway feel like I can do it quicker and easier with my guns. Even on Survival it's really easy for me to kill things, especially since I have a near infinite amount of most supplies. I'm hoping the survival update will make it it harder, because right now I don't even really use Stimpaks much. I have 1000+ of them in a wooden cabinet in Sanctuary, in addition to a mountain of ammo and a few hundred frag grenades (which I also don't use). I really should just max out my explosives perk and just go out with a large amount of mines and grenades (nothing else) and see what happens. 

I have gotten several hundred frag mines from playing this game, and yet I can't recall ever using one. I try to think of situations where they might be useful to me, but fail to think of any. I'm considering the idea of covering hostile locations with mines so that the next time they respawn and I arrive, they'll get blown apart. However, I'm worried my mines will disappear like the ones that enemies use. Do any of you have any idea what I should do with them? I could sell them, but I have enough caps already, and feel that using them would be more satisfying.

Thanks!
