This shows that the chances of all three biorhythms being greater than 89 are less than 1/3 of one percent.

>> t = (1:tzero)’;
>> y = 100*bio(t);
>> s = min(y,[],2);
>> k = find(s >= 89);
>> p = length(k)/tzero
p =
0.0035

It turns out that today all my biorhythms are at 89 or higher (How often does that happen?) – now I feel much better!
