Granted I have no idea how they got a measurement of 23.,(reply>), 23 is like dying of AIDS numbers,(reply>), Maybe 23 per something,(reply>), @ishtar van looy It's about the exacty the same as...the whole of Belgium.,(reply>), Wow, 23 whole T-cells! That's more than the entire population of the town of Barnstaple has, combined!
