Every now and again I'm reminded that I've been on the internet a very long time. Today it was realizing the phone number on my PayPal account is so old, the area code for the house it belongs to has changed - maybe twice. I've got addresses for houses on three continents in my Amazon account, and sometimes it's the only way I remember where I used to live. It's weird that my shopping account could bring me nostalgia. Of course, the email addresses also tell a story - that's actually a thing for a lot of us - aol to hotmail to yahoo to gmail to etc. I've heard it's sometimes used to determine the age of job applicants, and they urge people to be sure their address is up to date.
