I don't think it will be nearly enough to concentrate on the oldest among us to solve this problem. Although they are the overwhelming part of the population that would most probably die from it, the 40 - 65 are the age group that is most infected. Allowing people to think that the below 65 age group can go on as usual will curb the infection rate. At best, it might slow the rate at which people are dying but not the spread of the disease in general.
My opinion.
