Like the rest of us, Warren Buffett is adapting to life in a coronavirus world.

Buffett, who had been coming into work as of last week, may be changing his work routine because of the coronavirus. According to a Berkshire employee, Buffett “was in the office Saturday, and by the way, is feeling 100% fine. However, he said that he expects to be working from home tomorrow and will probably make that decision on a day by day basis.”

Last Tuesday I interviewed Buffett, who turns 90 this August, in his office in Omaha and asked him about precautions he’s taking right now so as not to catch the disease. Has he changed any of his habits or behavior?

“Well, I'm drinking a little more Coca-Cola, actually. That seems to ward off everything else in life,” he joked.

“I'm 89. I just had two different doctors tell me I'm in much better shape than I was a few years ago,” he said. “I'm not sure what I'm doing to get in better shape. I had an annual heart check where I wear something around my waist… [and] the guys said my — it's never been better.”

“In terms of changing my life, I haven't really changed a lot,” he said. “But I could work at home easily, and so could people in the office.”

Just to show you how fast things are changing, I asked him at that point if he was considering working from home?

“Well, not yet, no, no. But my doctor does tell me, don't do a lot of traveling into big crowds, and everything. But I have one trip scheduled now, and I'm not changing it.”

That was just a week ago.

Buffett may be taking a cue from economist John Maynard Keynes who said, “When my information changes, I alter my conclusions. What do you do, sir?”
