Frankie Muniz appeared on Good Morning America today to share some details of his shocking stroke at the age of 25.

"I couldn't say words. I thought I was saying them! My fiance was looking at me like I was speaking a foreign language," he revealed. Scary!

Not only was the Malcolm in the Middle star's speech impaired, his vision was affected as well. According to the actor, he was riding his motorcycle in Phoenix on Friday when he suddenly couldn't see out of one eye.

Doctors subsequently determined Muniz suffered a "mini stroke," which happens to fewer than ten percent of people under 45. His lifestyle was not a contributing cause, either! The engaged star swears he doesn't drink, doesn't do drugs, and has never had a cigarette.

"I can't get a deep breath in. I'm still trying to make sense of it, but I'm happy I'm alive," he added.

We're glad your alive too, Frankie!
