No, I've always had a weird thing about leftovers, it's the same thing with me being weirded out by home cooked food that wasn't made by me or my mom. I will eat leftover pizza if it's less than a day old, but that's it.
Depends on what it is. If it's pasta or curry or something that tastes good reheated, sure. If it's a burger I just make a point to eat as much as I can.
