I am some years off pensionable age (66 for me), but today I am tired and coldy and the arthritis in my knee and ankle are playing up and I am absolutely sure I must have a physical age of 66 or possibly older.
I've had a few health issues over the years and I'm sure that medical tests would establish a physical age of 66 or possibly even older. (The NHS's recent heart-age survey has already indicated this.)
So, armed with biological evidence that I am actually, physically, older than my birth certificate says I am, I would like to apply for all my records to be updated to my real, physical age, so that I can claim my government pension.
Can anyone suggest how I might take this forward? I don't think it's any weirder than suggesting a person can change sex. If they can get their birth certificate changed, why can't I?
