Never heard of moxie myself - interesting word. I had a DVR HD cable box that was called a MOXI - but that was a Motorola product.
Yeah - Tiger played well, all things considered. Being one who is familiar with sports injuries - if the ACL is torn (I didn't realize he has a complete tear) - there isn't much that can be done about it without being laid up for a few months. Usually they take part of the other knee's ACL or you can opt for a slightly used one from a cadaver....
Myself- I have a torn rotator cuff and pretty much need full reconstructive surgery if I ever expect to avoid dislocating my should on a regular basis - but, I am not doing any more damage by not getting the procedure done (I was told 10 years ago that eventually it's gonna have to happen) - So I made a choice, do I lay myself out for 6 months for surgery and recovery? Or put it off until I am less active?
For now - staying active, deal with a little physical pain now and again...
