My co-worker Chris, made the following observation. I suspect it was meant to be rhetorical, but I was curious:

you can follow dictionary.com on twitter… what for? A word a day for the rest of your life?? How far do you think we’d get? — Chris Shennan

Chris and I are both proud Scots, and were both born in 1982. For a Scottish male born in 1982, the average life expectancy is (a somewhat shocking) 69.1 years.

Combine that with the number of entries in the Oxford English Dictionary:

the Oxford English Dictionary [contains] approximately 301,100 main entries — Wikipedia

Sprinkle it with some Python magic:

import datetime

birth = datetime.datetime(1982, 5, 19)
age = datetime.datetime.now() - birth

life_expectancy = datetime.timedelta(days=(69.1 * 365 + 69.1 / 4))

print float((life_expectancy - age).days) / 301100

And we get the following morbid answer: if I started to follow the dictionary.com Twitter account today, and died on schedule, I’d get through 5.06% of the O.E.D.
