Forty-year-old leftovers

In an effort to make some new space in the basement, I pulled out and
opened a trunk that I had not opened since the late 1970s. Among other
things, it had some of the paraphernalia from my back-packing and
hitch-hiking days of that decade. Part of that stuff were these two tins of
preserved fish, still a favourite food of mine, and a staple when I was on
the road. The kippers tin was already label-less and loose-keyed when I
packed it away, so it may be more like 45 years old

The tins are a bit rusty but they aren't leaking or bulging. Hmmm. . .
maybe I should try it.
