It just floors me when I see people who have a picture of themselves in a judo gi on LinkedIn - and their profession is listed as Project Manager, accountant or software developer. (If you are a professional judo instructor, then it is completely understandable, but these people are not.)
It's bad enough when the person in question is someone young who has recently retired from competition and may not have a lot of professional accomplishments yet. It's still not correct, but it is understandable. When the person in their judo gi is over fifty years old, it just floors me. Seriously, what are you thinking?
Before you point out that, in fact, I have my picture in a judo gi in my profile, let me point out first that this is my PERSONAL blog. I am founder and president/ CEO of two companies. You can see my bio for The Julia Group here and there is nothing there about judo because it is irrelevant.
Above is a photo of my very dear friend, Dr. Jacob Flores. The relevant point here is that he is giving a lecture to staff from a vocational rehabilitation project on symptoms, treatment and prognosis for patients with Type II diabetes. A second relevant point is that he has an MD, is board certified in geriatrics and treats predominantly patients with chronic and terminal illness, with a high proportion of individuals with diabetes on his caseload.
The fact that he is a fifth-degree black belt and had two sons on the world team is totally irrelevant, even though he and I were both in this meeting.
You know where judo is on my resume? Under publications, I include the book I wrote, Winning on the Ground. That's relevant because it shows that I write well enough that someone would publish a book by me. Of course, there are a lot more publications listed on things like comparative factor structures.
When I see someone in a professional setting - say on their resume, company web page, LinkedIn, etc. highlighting their martial arts expertise instead of their professional accomplishments, it leads me to assume that they haven't achieved much professionally, otherwise, they would be talking about that.
