Like you say, if you are over 70 and get it, your mortality rate would be more like 10%, even with these lower numbers. > This makes a lot of sense as the earliest numbers were based only on people presenting severe symptoms, and huge quantities of people with nCoV are completely and totally asymptomatic. Isn't another possible explanation that it simply takes very sick people a few weeks to die from it, so if you start counting a week farther back then the confirmed-then-died rate will be higher? (Due to undercounting of people who are going to die from it but haven't yet.)
