Ok, I like tennis ... it's a fun sport to play and it's quite a work out ... but it is NOT for me! We were playing this morning and who but me decides to completely crumble and now I have to go to the doctor later this afternoon ... as the nurse said, a crunching noise is never good while playing tennis What kills me is I can't drive! this is just lame! ... I will keep you all updated on my condition later today.
