I fell twice this year, Once a hole got me, and once in cattails.  I dropped a rooster right in the middle of the cattails.  Dog raced all around in them but nothing, so I walked in try to find it.  Feet got tangled, tripping me, and down I go.  GF can't see me so is yelling "Are you alright?"  Fought my way back to my feet and walked out, only to discover the cord holding my dog controller had broken, so I had to go back in to look for it.  Fortunately it is orange so I found it where I had fallen.  GF and I repaired the cord/lanyard.
Dog, who we had not been paying any attention to, casually strolled out of the cats with the rooster in his mouth.  
 
A few years ago when I hit 70 I noticed that every time I went to a doc they asked me the same question -- "Have you fallen lately?"  Now I'm starting to see why, as I even find myself losing my balance for no apparent reason in my house.
But I am spending a lot of time conditioning, and especially my legs, to be ready for bird hunting season.  Lot of knee-bends and 25 minutes on the elevated treadmill 3-4 times a week.  I am also trying to pay attention to where every step is landing, to avoid holes and obstacles.
I also switched to a super-light mid-height boot, which helps avoid leg fatigue which causes falls.
But if you are going down, be careful about fighting it -- that can result in torn ligaments.  Best to just relax and go down, only hurting your pride.
