Hormones

There’s something unique about hormones
Those molecules we can’t control
That pace through our blood with a vengeance
Like marshals about on patrol
On missions to regulate systems
To alter; to change and effect
Chit-chatting ‘tween tissues and organs
Whilst keeping all else just in check
And whilst bringing about homeostasis
They pop up adapting the way
That we think, act and be; so hormonally
In a signal parade every day
