Every cloud has a silver lining. Here are three positives that might come out of the Coronavirus pandemic.

• Telemedicine is finally being covered by Medicaire. Medicine comes into the 20th Century. It will be difficult to roll this one back after the crisis.
• Online teaching is being tried by millions. The teaching profession has resisted this technology for a generation. This crisis might break the logjam.
• The Buffet is over. Social distancing has taught us that the “sneeze guard” on the salad bar protects nothing.
