After suffering an irregular heartbeat and shortness of breath, Marvel Comics legend Stan Lee, 95, was taken to the hospital Wednesday, according to TMZ. He was released Thursday and told KABC that he’s feeling great.

“It’s nice to know that somewhere in the world there are still people who care about what I say or do,” Lee said.

He is expected to carry on his normal travel schedule this week. Last year, illness got in the way of two of Lee’s major appearances at comic book conventions, according to KABC.

Many fans tweeted their hopes that Lee would recover soon.

“Stan Lee is truly a superhero. 2018 don’t you dare,” one fan tweeted.

Lee recently turned 95, and he is known for co-creating Spider-Man, Iron Man, the Hulk and the X-Men.
