I would love to take credit for coming up with “Age-fluid,” but I’m stealing it from Chip Conley, who I saw speak at Transform a few weeks back. Chip was talking about age diversity and how only 14% of the F500 actually measure age diversity and how this is becoming a major issue in corporate America.

Now, if you would talk to my wife, she would tell you I’ve identified as “age-fluid” most of my life. I’m 53, but my humor is mostly that of a 12-year-old boy! Also, I refuse to believe that I still can’t do most of the stuff I could 20 years ago. While my body feels like it’s 80 some days, I still think I hang on the court with folks half my age.

For hundreds of years, we’ve known of this phenomenon where you have a mental age and a physical age. I’ve already said my “mental” age is way lower than my physical age, but it’s important to truly understand the impact this has on the diversity of our organizations. Because we also see the opposite. I’ve met many young people who were wise beyond their years and seemed to have an “old soul.”

Most organizations and hiring managers are biased toward those of a higher age. I don’t think that is shocking to anyone. Old people are still the ones we can be biased against, and no one thinks it’s wrong. We make jokes in meetings about someone’s advanced age all the time, and no one thinks anything of it. But in reality, this is no difference from someone making an old person’s joke than if they were making a similar joke against someone’s gender or ethnicity.

I actually love the concept of being Age-fluid.

If someone in our society can be gender-fluid and decide from day to day which gender they believe they are, then I can decide what age I believe I am. I mean there are advantages to every age. Being young is cool, but it also sucks because you don’t know what you don’t know. Being old can suck physically, but usually you’re also more confident in where you’re at in life. You know who you are and you’ve come to grips with it. Being a child is magical, but you don’t understand that.

Today I feel like I’m 36.

Why 36?

Hmmm…well, at 36, you can still feel great physically, but you also have enough time on this rock to have a bit of learning. I won’t call it wisdom, but you’ve made enough mistakes to mostly know how not to make them again. Doesn’t mean you won’t, but you know the path you’re going down and how it will most likely end.

At 36, you aren’t looking at the end yet. You also aren’t looking back at the “good old days.” You feel like you still have more life ahead of you, than behind you, and you’re still young enough to truly feel like you haven’t written the script for your life yet. You still have promise, and you’ve made a bunch of progress on where you want to go.

Yeah, today, I’m 36. I’m also about 12 for a few seconds at at time, depending on what memes my other 12-year-old friends are sending me!

What age do you want to identify as today and why? Hit me in the comments.
