I would have to agree that architecture tends to be much less impressive when viewed through a microscope than when you can see more than a square inch of it.

The implication appears to be that indoor swimming pools contain disease, but obviously they would not differ from any other swimming pools in that respect. That is the reason for the chlorine that makes getting swimming pool water in your eyes so painful.

You're mostly spot on but your last sentence is flawed, as it's chloramines that are the problem with pools, not chlorine, and urine is all-too-often the root cause

From the article, reasons why chloramines get created:

> perspiration, oils and urine that enter pools from swimmers’ bodies.

I choose to be an optimist and will believe that list starts with most common source and ends with the least common.

According to the article, chloramines come from the reaction of pool chlorine with human urine, sweat, and body oils.

It seems like that would still be happening in the absence of urine?

They did, that's the problem
