Yesterday I was shocked to learn that another worker who actually works on other side of my work cube, has sustained head injuries after she went swimming probably in strong waves down in Mexico.

She's had some strong headaches and so they scanned her head. X-rays show some dark spots, injuries.

I don't know how to swim, so I don't know about this type of injury. I was shocked actually but dearie reminded me of the possible velocity and impact of rolling ocean waves.
