My Get Up and Go Has Got Up and Went

I'm getting old I'm in despair
I've found my first grey pubic hair
I'm fast asleep by half past 10
I'm never gonna see my teens again.
I want to live till I'm 99
Where's it gone, this life of mine
How can it be, that  I'm way over 40 something 
I think of retirement beside the sea.

How do I know that my youth is all spent?
Well, my get up and go has got up and went,
But in spite of it all I am able to grin.
When I think of the places my get up has been.

Old age is golden, So I've heard said
But sometimes I wonder, as I get into bed.
Not looking forward to having  my teeth in a cup
And my eyes on the table until I wake up.

Sleep dims my eyes I say to myself
"Is there anything else I can put on the shelf?"
And I'm happy to say as I close the door
"My friends are the same, perhaps even more."

When I was a young thing my slippers were red,
I could kick my heels as high as my head.
Then when I was older, my slippers were blue,
But still I could walk the whole day through.

Now I'm still older, my slippers are black.
I walk to the store and puff my way back.
The reason I know my youth is all spent,
My get up and go has got up and went.

But really, I don't mind when I think with a grin,
Of all the grand places my get up has been.
Since I have retired from life's competition
I busy myself with complete repetition.

I get up each morning and dust off my wits,
Pick up the paper and read the 'obits',
If my name is missing I know I'm not dead
So I eat a good breakfast and go back to bed.
