Thinking of changing my email address

It’s a shame it’s so much hassle to change my email address and scrap inbound email to one of my older addresses. Things like having to let all my friends know the new one and adjusting mailing list subscriptions etc. I’ve got several legacy addresses that seem to be the primary sources of spam arriving in my mailbox but I just can’t deal with scrapping them. The effort of deleting spam doesn’t yet outweigh the effort of figuring out who’s still using that address to send me email.
Do people really click on links in junk email about viagra, cialis, online pharmacies, texas hold em, casinos and online gambling and betting? I guess they must otherwise these spammers wouldn’t carry on spamming.
