In the UK news papers today there was an article about how much tea the average Brit drinks in their life time*. The total they came up with was 74,245 cups of tea. That works out to about 1060 cups a year or 20 cups a week or 3 cups a day. Now in our household you could easily multiply this by 4, giving a staggering 203,840 cups in a lifetime.
But to let your imagination run wild try guessing how much tea Roz can guzzle down. I was going to estimate a figure but my calculator started pleading for mercy

I just think it is fascinating how much of something we can pack away in a lifetime, be it tea, coffee, chocolate muffins or those little tiny dognuts you can get from Greg's with the cinnamon sugar

(yes everyone outside of the UK should be very jealous now
