[00:00:01]I'm going to show you a clip from one of Joe Rogan's shows. Now, I don't like Joe Rogan, but I'm using this clip because it has reference. Obviously, it talks about what it is that I'm talking about in this video. I had no I went and looked this up after I saw this and it turns out to be true. Um, but I had no idea that actress Mary Lou Henner I best know her from her role in Taxi, obviously, but that she had a like an extraordinarily rare photographic memory.

[00:00:34]We were talking about Mary Lou Henner from Taxi the other day. What's that disease she has? It's not a disease.

[00:00:39]It's the opposite of a disease. It's an amazing ability. Highly superior autobiographical memory.

[00:00:44]>> Mary Lou Henner has always been famous for remembering everything.

[00:00:50]Hey Mom, what day was Valentine's Day in '79?

[00:00:53]It was a Wednesday. And you're right.

[00:00:56]You've never explained how you do that.

[00:00:58]I don't do it. I just see it. And you can remember your whole life? Yes, I can remember my whole life.

[00:01:03]>> Mary Lou is one of just 10 people in the world who've been tested and proved to have superior autobiographical memory.

[00:01:12]October 1st, 8th Total recall of every day of their lives. Extremely impressive.

[00:01:18]>> Delta Airlines flight 191 crashes near Dallas, Texas.

[00:01:21]>> Oh, I know exactly when that happened because it was August the 2nd of 1985.

[00:01:25]It was a Friday. Such a gift has never been documented before.

[00:01:28]>> Hey, cuz you have that awesome memory where you don't forget anything. I have highly superior autobiographical memory, like Mary Lou Henner.

[00:01:35]And Most people, if you ask them, remember eight to 11 events within any given year. And people with HSAM, we remember 200 to 365. The criteria cut off is 200, although I scored in the 99th percentile with 365 because I can do a whole year. I have highly superior autobiographical memory. It means I remember everything that happened every day of my life.

[00:01:58]>> Wow. That must be excruciating. Your life is pathetic. That's exactly what you said the last time I told you.

[00:02:04]April 8th, 2012 That's right.

[00:02:10]That is amazing.

[00:02:13]That she has total recall of every single day, every moment of every day of her life.

[00:02:23]One of They said 10 people in the world.

[00:02:28]That is crazy.

[00:02:30]Crazy.

[00:02:31]I'm going to go out on a limb and say she never really had much trouble memorizing her lines. She could probably memorize and coach the lines for everybody else as well.

[00:02:40]But, yeah, I mean, wow.

[00:02:43]Did you guys know that about Mary Lou Henner?

[00:02:47]Just I I would love to just sit down and like test it over and over and over again knowing she's just going to keep give me the inventory number for a bumper bracket for a '74 Volvo. She's seen it. She'll going to She's She's going to remember it, for crying out loud.

[00:03:04]That's crazy. It's amazing.

[00:03:07]Absolutely amazing.

[00:03:09]365 I didn't know that about the average person, either, how many events that they're going to the average person will remember over the course of a given year.

[00:03:21]Doesn't seem like a lot, does it?
