Many viewers of Bill Clinton’s prime time DNC speech Tuesday night noticed his hands were shaking repeatedly throughout his performance.

“Anyone else notice the shaking hands on Bill Clinton?” Twitter user @QueenMuse1 posted. “Think he’s sick?”

Yes, others noticed, too:

He's older, health problems, did you see his hands shaking? Bill Clinton was amazing tonight. It was historical. @chrislhayes — Debra Notachance (@DebraTweets) July 27, 2016

It’s been an ongoing problem for the former president.

During an appearance in Fairfield, Iowa in January, Clinton’s hand was visibly shaking as he launched attacks against Bernie Sanders.

“Who will do the most to make you a part of the future that the president painted in the State of the Union,” Clinton said, his voice quivering, too. “How are we going to do it and who’s the best change maker to do it?

“It’s not close. Hillary is the best change maker to do it,” Clinton said, his hand shaking as he pointed at the audience.

The once energetic Clinton is showing his age. It’s not 1992 anymore.

In 2013, Clinton denied having Parkinson’s.

“I have a condition that sometimes you get with aging,” Clinton said at the time, the Huffington Post reported. “You may have noticed it; my hand has a little tremor when I’m tired and a lot of people do when they’re older.”

“The first time it happened, I had to go get myself checked to make sure I didn’t have Parkinson’s [disease],” he said.

He said his doctor claimed he didn’t, though Clinton didn’t say what condition he has.
