The swimmer jumped into the water.
He wanted to swim across the pool in less than a minute.
While he was racing across the pool, he was struck with a cramp in his legs.
The swimmer became nervous and agitated because he was gradually moving slower.
When he reached the other side, he crawled out of the water.
"I don't get it!" he said. "I've never gotten cramp in my legs before!"
He dried off, dressed, then limped out of the building.
That night, his temperature rose to 40 degrees! He caught a cold in the pool.
"My head is feeling light/I'm feeling light-headed," he said.
