Acorns

I went to the dentist this week.  My dentist had major surgery on his arm/shoulder.  He said he ripped a couple of muscles off the bone.  I asked him how he did this.  He said he was taking the trash out and slipped on an acorn and landed wrong.  This reminds me to be very careful of my footing when running.  Acorns can be hazardous to your health.
