TaT and Phool, I'm with you guys, I know that there are certain type of situations where the extra magnification and especially the larger objective really helps. I have been down in a draw on the backside of bigger mountains and it gets dark many times before shooting hours are up.
I think many people here are thinking primarily of big game scopes only. What about yotes at dusk and dawn? I'll Take any advantage I can get.
I know what you mean about hunting in states until you just can't see as well. Try pig hunting in Texas. With that big 50 turned down to about 4x-6x you can see very well on a full moon, without having to spotlight them.
I hunted with a very good fixed 4x scope for almost 20 years and never had the coin to go bigger, once I did I went with a Burris Black Diamond 4x16x50. The difference was like dial up and cable internet. It was nice to be able to take a look at an animal a mile away with out breaking out spotting scope or some gigantic binocs; not to mention being able to judge it as worth persuing before you got all the way over to it.

Not missing those days.
As for the going blind thing Red, well I've got better sight than most people I know. So for me I think that's

But I'm sure when my sight starts to fail me I'll have some sort of telescope strapped to my shooter just to make me feel better

As stated earlier in the thread somewhere, it is all what you are comfortable with and what you prefer.
