When to Retire from Huntting ???

[Westerner2]

When do you retire from huntting.I am 69 and about wore out.Back,Knees Haert and Lungs.I am only good for about 400 yards with Oxygen if I am under 7500 FT.
Shooting still not a problem.I still shoot 2 1/2 gropes at 300 yards with anyone of 6 Rifles
My girlfriend is on me about all of the time.I tell her if I am going to Die.I want to go with a Rifle in my hands an my boots on.Then she won't takl to me for week or so.
So what do I do ??? Westerner2
