Why is it?

Why is it? When you get old
Everything starts to dribble
First it’s your nose, then your eyes
Then parts below the middle
When safely snoring on the couch
Wake up with a mouth full of spittle
After wiping your chin, with a silly grin
There’s a need to rush off for a piddle
Where does this liquid come from?
That is a mystery and a riddle
 
Why is it? When you get old
 All you bones begin to creak
Physically want to do lots of things
But your body is too damned weak
You take a look into a mirror
And discover deep lines in your cheek
Waaah!    Is that me?, you scream
No!  It must be some other freak
 
Why is it? When you get old
Your body stretches and gets fatter
The false teeth in your mouth
Are loose, rattle around and clatter
You forget things and can’t recall
Just as long as you keep up the chatter
Then others won’t judge and think
You’ve lost the plot, gone mad as a hatter
As long as you’re happy within yourself
The rest doesn’t really matter   
Lol.
