Depends - is this called fun?

I have a bad terminal disease
There’s no cure to make it go away
It’s been here since the beginning of man
so I think it’s destined to stay.
Being both mental and physical
The disease is called unique
Not being able to stop it at all
Remember - 50 years is called antique.
For me, it started the other morning
As I took a good look in the mirror
Seeing lines drawn all over my face
“need my glasses to see this shit clearer!”
My hair was turning a lighter color
And looking kinky like pubic hairs do
And I could see I was growing a beard now
These are all symptoms to name a few.
I got brave and took off my clothes
Decided to glance in the mirror again
I knew better-should have never done that!
My stomach was now another rear end!
Looking down at my frontal butt
I can see my feet are a wee bit fat
Doctor said “your thyroid is broken”
“It isn’t producing this or that.”
Then there is the grand illusion
In the mirror you don’t see you
And time flies faster and faster
Soon you’ll know this to all be true!
The disease I have is called aging
one day soon you’ll experience the same.
Life is really not that long my friend
any regrets you‘re the only one to blame.
And that shit they call the “golden years”
that term is wrong and a twisted one
it’s because you now piss on yourself
depends – has the fun just begun?!
