Why is it so important your keypair be as long-lived as possible, when 
there's very little likelihood of you going for that long a period 
without a key compromise event?

Think about key compromise events as you would a building fire.  We 
don't make our buildings fireproof: instead, we clearly mark fire exits, 
hold drills, make backups, and write continuity-of-operations plans.  
The fire *will* happen, but how quickly we recover from it is up to us.

Murphy *will* find us, Murphy *will* beat us, Murphy *will* take our 
lunch money.  When making a new keypair, I think people are well-served 
to remember the key lifetime is fundamentally in Murphy's hands -- not 
theirs.
