Billionaires are just similar to us. However, when it comes to the unpredictability and stress of 2020, that statement couldn’t be further from the truth in most situations. Even the richest among us are struggling. And the stressed billionaire of them all? Bill Gates.

Even if you consider yourself empathetic, determining someone else’s stress levels might feel like an difficult task. Well, there’s actually a possibility to do it — kind of. It can be done by simply using a tool, which is developed by Mike Thelwall, he is the professor of IT at Wolverhampton University, talent innovation company SHL ranked prominent business leaders by how “stressed” their recent tweets have been.

The tool is named as TensiStrength, and is used to check the stress levels in tweets by analyzing them on a scale of -1 (no stress) to -5 (very highly stressed). It is basically based on the classification of words related to stress, frustration, anxiety, anger and negativity. Further, it ranked the business leaders (chosen according to how often they appear in the news and on social media) based on the amount of tweets they posted between January 1 and June 30 that classify as “low stressed” or higher (-2 to -5 on the Tensi scale.

Bill Gates tops the list, the tool determined 20 percent of his tweets this year could be classified as low stressed or higher. Close behind him at 19.3 percent is Oprah Winfrey. Here are the other leaders who made the top 10.

Only one CEO didn’t make the top 10?. He was Elon Musk, he ranked 19th among the business leaders studied. Though he’s a prolific tweeter, only 5.2 percent of Musk’s posts qualify as low stressed or higher.
