How to know when you are old

Everyone is obsessed with staying young these days, and I have discovered the secret to knowing if you are truly an immortal youth.  We've actually had winter this year: feet of snow, multiple blizzards, and then severe cold.  After all that, a certain four year old of my acquaintance insists he still loves snow, and I had to agree with him, as a kid, I loved snow, and anxiously awaited those glorious snow days when it was too nasty to go to school but I could go outside and play.  That's the test: do you love snow, does a blizzard inspire dreams of sledding and snow forts or do you groan about the impending shoveling?  If you love snow, congratulations, you are still young!  If your climate is not conducive to snow, you'll either have to move (ski vacations don't count, you have to live with the stuff for months on end) or discover some other metric.  If you are really determined about this, I can always use help shoveling so I'd be happy to help you out!
