eastender ) gurgled happily, sounding much like they
were saying :

Your original claim was that a lower proportion of those using taxis
would be likely to be affected than the population at general.

We are not talking about proportions of taxi users, but I think that's
just your bad English.

Not mine.

What I said was:

'People who take taxis are less likely to be those affected by living
near heavy traffic.'

Exactly.

Let's say 50% of people are affected.

For taxi users to be less likely to be affected, less than 50% of them
would be affected. I'm suggesting that is not the case, and you're
interpreting that suggestion to mean that taxi users are 50% of the
populace.
