I think I'm laid up for awhile now.Picture this,,,an 80yr. old up a ladder pruning limbs when the ladder decides to move.I'm about 16ft. head high up this tree and I begin to do ackrobatics.I feel in a sitting position forcing my legs under me.I have no broke bones but 2 big swollen knees and can't walk (the pain).As I lay on the ground thinking what a nut I am I did Pray to HIM and give thanks for keeping me.My kids and the wife have laid the law down to me.NO more climbing !!!! I think this is great advice.
