If one of your Gen Z work colleagues really wanted to find out how old you are, they might only have to look at your email address. For example, when Gmail first became a thing, it was invitation-only, and it was easy to get an email address with just your first and last name at Gmail dot com. No additional letters, numbers, or symbols needed. That’s a sure sign that you’re “of a certain age.” Then, there are those people who still haven’t managed to update their email preferences, and are still using AOL, Earthlink, or some other prehistoric email platform…all of which also serve as a way to date you more than you might be comfortable with.
