You should very rarely generate a new keypair.  As for the security of
your keyrings, that pretty much depends on the security of your
passphrase; we have to be able to move keyrings from machine to machine
otherwise we're only identifying machines, not ourselves.

When I first got into PGP I went hog wild and created keypairs for every
email address.  I came to regret it.
