Spirals (a 20 year old remnant...)

I am spirals.
I see the best and worst of me
Periodically.
The twists and turns of my life
Pass by overhead
But I can't meet again,
Relive,
Those curves above,

Sometimes, though, I catch a sense
Of personal past,
And mirror in my next descent
The motions lived before.
And craning, scarily, 
I can see
The start of me
Piercing eternity above.
