The chill of my age

With my mouth open, I doze in a garden chair, trying to warm my bones
in the Sunday morning sun. Is this the first sign of ageing—the chilling
fact that I am freezing in August? I know that this is the north of Scotland,
but still. And with all due respect, I am only slowly approaching my fifties,
not my nineties. I am nothing like all the elderly folks passing by my place
on the way to the nearby church. To be honest, they somehow seem more
alive.
