|My mother is 93 years old. Thankfully she is quite healthy for someone of that age, and she lives in relative comfort in a nice retirement home in Johannesburg. I last saw her about a month ago – she looked well, given the circumstances. But I am rather concerned about her today: I am concerned, because at her age, she is probably a lot more at risk of coronavirus and its deadly consequences than most people around her. We’ve all seen the statistics: if you’re lucky enough to be younger than 50 today, chances are that, even if you do get Covid-19, it probably won’t affect you too much. But for anyone older than that, the risk of a bad outcome starts to increase incrementally as your age goes up.
