Invincible

We feel it.

Strength. 

Youthful. 

Energetic. 

We don't feel it. 

Weakness.

Time passing. 

Sickness. 

We are invincible. 

We are young. Or are we?

We don't see it coming until the sparkles become white and the lines become deep. 

When does it happen? A moment? A process? When does youth turn to maturity? When do our bodies betray us and let gravity do more than keep us grounded? When do things clog and thicken? 

Aging. 

We are invincible. 

Until... We are not.
