I just sent more-or-less the following in an email to a friend and colleague:
On a personal note: I’m impressed that you’re letting yourself go gray (you look great, btw), and are bragging about having professional experience since 1992. For the past couple of years, I’ve internalized advice about distracting people from my age. I listed my experience on LinkedIn as “more than 15 years” and I was careful to avoid pop culture references that might date me. Then a month or two ago I decided I didn’t want to be that guy anymore. I even made a Phil Donahue reference at a company all-hands meeting.
It helps that I’ve gotten fit. If some 25-year-old ectomorph wants to make wisecracks about my age, I can trounce him. Or if he proves tougher than he looks, I can run away and not get all winded and stuff.
My college paper used manual typewriters, and on my first job out of college, I worked for a newspaper that used a minicomputer-based system with 8″ floppy disks and greenscreens. Now I’m a social media professional. That’s not a liability, it’s my superpower.
