stop using mathematical models to predict situations where humans are involved ... which means, most of the situation that we deal in life.
math based on symmetric nature of number-line cannot be used to project / predict any situation where humans are involved ... which ended up resulting in a disaster in case of second wave of corona in India.
second, we are dealing with a virus, which requires humans to take an annual cocktail; so we can co-exist .. the vaccine that people are given doesn't have much use, although i am not against it, as its there to fix last years' version (Q1 2020), & we are dealing with the next version, as the virus has moved on, while humans are still stuck w/ solving last year's problem ... as you can imagine the flu shots are given each year; plus, the flu and the shots typically arrive at the same time, & still people die, when there is a mis- match or mis- timing.
BL: unless we coincide with the version of virus, we have no control on the problem .. & we are no way near that state .. but likely by the end of this year, IF people learn a few things ..!
