Customizing or Refining

It's funny how just about everything in a human being slows down as you get older. Not that I am experiencing this as you see, I am a young man, but I do observe people like crazy.
Your reactions are a little slower than they were before, you don't even laugh with the same rhythm anymore.
And the main thing is, when you sign something on a sheet of paper, your signature is not the same, and it's not even because you are incapable of writing.
You know when you first learn how to write in cursive, the teachers were always hard on you about making your handwriting legible. Then you write your name down on something, and it be so neat.
But the more you write your name now, the less you can understand it. Some people are so bad that they can't read their own handwriting. They be asking whose signature is this, not knowing that it's their own.
It's like at first, when you start customizing your own name in writing, you write all of the letters out in perfect cursive. Then, you write out all of the letters except the last letter. You just put a nice little line at the end of your name.
Then, as time goes on, you will soon write your name with less and less letters written out. It just be the first letter written out, then just one big line at the end of it.
That's not customizing your name anymore. It's more like refining your name. You know why we write our names out like that? BECAUSE WE ARE SICK AND TIRED OF WRITING OUR FREAKING NAMES, period.
