First heard this in my early 40s, when 50 (half a hunner) seemed awfully old: now it really seems quite juvenile!
You can change the age to suit any level of Old Fartdom too!

FREEWHEELING                        by Jim Reid

I'm getting ower the hill it seems, though my hert it still feels young,
They say when half a hunner's here, your flings should a' be flung.
But I've some flungs I've yet tae fling afore I ends ma days,
And so I don't want to hear you say that "Old, he's past it" phrase.

Chorus
Freewheeling noo, Freewheeling noo, gets easier every day,
Just tak it slow, where'er ye go, freewheeling doon the brae.

I used tae climb the highest hill, I used tae dae sae weel,
But the view is bonnie, e'en frae here, ye're jist as high as ye feel.

Chorus
Freewheeling noo, Freewheeling noo, gets easier every day,
Just tak it slow, where'er ye go, freewheeling doon the brae.

My eyes are gettin' dimmer noo, and specs I ought tae wear,
But there's some things I see clearer noo, and ye cannae ask for mair.

Chorus
Freewheeling noo, Freewheeling noo, gets easier every day,
Just tak it slow, where'er ye go, freewheeling doon the brae.

We've a' tae go a different road, though it may seem hard sometimes,
So let's try to help oor neebour tae get ower his stiffest climbs.

Chorus
Freewheeling noo, Freewheeling noo, gets easier every day,
Just tak it slow, where'er ye go, freewheeling doon the brae.
Freewheeling noo, Freewheeling noo, gets easier every day,
Just tak it slow, where'er ye go, freewheeling doon the brae.
