The actor who is married to Mila Kunis, made this revelation that he had been suffering with this disease, which affected his ability to hear, see and walk. Kutcher stated this during an episode of Running Wild with Bear Grylls: The Challenge.
Kutcher also revealed that this ordeal has given him a newly found sense of perspective.
"Like two years ago, I had this weird, super rare form of vasculitis, that like knocked out my vision, it knocked out my hearing, it knocked out like all my equilibrium", Kutcher could be heard saying in a clip from the episode. "It took me like a year to build it all back up".
"You don't really appreciate it until it’s gone, until you go, 'I don’t know if I’m ever going to be able to see again; I don’t know if I’m ever going to be able to hear again; I don’t know if I’m ever going to be able to walk again", the Two and a Half Men star added.
"I'm lucky to be alive".
Kutcher also revealed that life got "fun" for him, when he started to open up about his "problems".
"The minute you start seeing your obstacles as things that are made for you, to give you what you need, then life starts to get fun, right?", the 44 year old added. "You start surfing on top of your problems instead of living underneath them".
Ashton Kutcher and wife Mila Kunis share two children together, 7 year old daughter Wyatt and five year old son Dimitri.
