This would be very unfortunate if it did result in a early retirement.

But I suppose better than never discovering it all and resulting in worse later.

I am a little puzzled about why Houston wouldn't have discovered this.

These guys go through all kinds of medical tests year in and year out and I wouldn't think this is something that just pops up out of nowhere.
