If you live long enough, you see almost everything. In all the years I have been on various posting sites, I've never seen anyone start a thread about their own birthday. I wouldn't have the guts to do that for fear of what would happen.
Not saying it is good, or bad, or anything. No real opinion on it at all. I'm only pointing out that it is just another thing I can say I have seen in life. Just another checkmark in my brain, so to speak.
Happy Birthday dude. May you live to 120 years old.
