People have been resilient throughout history, some viruses heavily effect the young who might have a bit more strength to fight it off. Covid happens to heavily affect those over 60 years old. We're into the second year now of living with Covid and some say it may even have been circulating around October 2019. The speed with which multiple vaccines has been produced is a great thing and will really help the world get back to normal - it's just the gearing up needed to protect 7+ billion people is huge. Bill Gates has been talking about viruses for many years and clearly stated they were the biggest impending threat to humanity, shame he didn't take a bit more action to prepare for them with the huge funds his charity sits on. Give it a couple years and everything should be back to normal, hopefully the injuries it causes can be cured through time.
