What is Normal?

One of my favorite lines from one of my favorite songs is,

He not busy being born is busy dying

Is there a normal?
When people say, 'the new normal' it's a cop-out. 
Yeah, I'll keep one of my wife's handcrafted masks
around my neck for a while.

'Let's go back to normal,' others say.
Really? what is that? Like saying, 'It's always been that way.' 

There is no normal. 
My uncle eats three cookies for breakfast every day.
He has farmed his forty acres for sixty years. 

Eating a midnight meal is normal for me. 
YThis peaceful feeling inside is wonderful,
but it's not normal.
