Answer 1

I can't speak for YOU, but I sure as heck don't want to eat something that's been exposed to air while it's in a can.  The VAST majority of non-plant organisms on earth require oxygen to grow, and plants require carbon dioxide, which is also abundant in the atmosphere. I'm not about to eat anything that's been stored long-term that hasn't been properly vacuum-sealed!!
