Pensieve header: Per-class Evil Virus risk assessment.

Numbers as of July 29, 2020.

P =2.93*(10^6); (* Population of Toronto *)
n = 30;  (* Daily EV cases in Toronto (rough average of last 7 days *)
d=56;   (* number of Ontario deaths for males 50-59, from [1] *)
c=2771;   (* number of Ontario cases for males 50-59, from [1] *)
a=2;    (* Adjustment to mortality rate due to the risk of serious disability *)
f = 0.5;  (* Fraction of the risk to me that can be attributed to teaching *)
Y=30;  (* My expected remaining lifetime years, disregarding EV *)
M=365*24*60*Y;  (* My expected remaining lifetime minutes, disregarding EV *)
R=((f a d n M)/(c P))  (* Reduction in minutes to my adjusted life expectancy due to teaching one class. *)

If R is close to 60, I may refuse teaching, on selfish grounds.
