The wonders of canned meat

Spam. Chicken of the Sea Tuna. Vienna Sausages. These are the canned meats I eat. One thought that often comes to mind when I pop the top off my favorite canned meat:
How old is this meat, and how long could this meat have stayed in the can had I left it to it's own devices?
Then comes the next question:
Could a person put themself in a can and remain in a sort of stasis similar to cryogenic storage?
Of course these questions are moot by the time I finish my canned meat, mostly because I stop caring.
Thank you, until next time...
