;) I've had my email address for 5 years and I hated having to change it before then, but as my Uni account was going away, I had to.

I recently bought a new mobile phone and had to swap my phone number into a new SIM card. Surprised the heck out of the people at the store that I'd had the same phone number for the last 4 years - apparently they're used to people switching them all the time.
