People have been writing about the relationship between T and coffee
from time to time.  How about the relationship between T and tea?

Tea also has caffeine in it.  It thus should affect our T the same way
that coffee does.  But many of us do drink coffee with cream a/o
sugar, while most tea drinkers---at least almost all Chinese tea
drinkers---don't use cream and sugar.

Would the difference lie in this cream/sugar content?
