OTOH the Bic lighter I found on a frosted park lawn a few winters back still works fine. Matches have their place...
Love my Bics too, and wouldn't be without one (or two or three).
Longevity is a real issue, though. Mostly it's about exposure to moisture over time, making the flint swell and fail. When kept in airtight packaging, they seem to last in storage for an almost indefinite period.
