This poem by James Simmons perfectly describes the ageing delusion and our sentimental feelings.
When I look in the mirror there is some young fellow lurking in my familiar features who bears no relation to the harsh reality of photography.
Art and Reality by James Simmons
From twenty yards I saw my old love
Locking up her car.
She smiled and waved, as lovely still
As girls of twenty are.
That cloud of auburn hair that bursts
Like sunrise round her head,
The smile that made me smile
At ordinary things she said.
But twenty years have gone and flesh
Is perishable stuff;
Can art and exercise and diet
Ever be enough
To save the tiny facial muscles
And keep taut the skin,
And have the waist, in middle-age,
Still curving firmly in?
Beauty invites me to approach,
And lies make truth seem hard
As my old love assumes her age,
A year for every yard.
