Very busy and Billy's Bootcamp

We had to handle about 90 patients by three pharmacists.
I hope we didn't make any mistakes.

At night I worked at emergency medical center.
There were not many patients.

One of the co-workers said she's trying "Billy's Bootcamp".
It looks fun to me because they look like dancing.
She said it was too tough.
I want to develop my muscle, so it may work.
