Natural decay ?

It says "Natural decay".

Natural decay, I agree. (Old age?)

Yes I would assume ‘natural decay’, as in very old and coming to the natural end of their life. Was the person elderly?

Yes. My mum died 10 yrs ago at a good age and for the cause of death the GP wrote "Frailty of old age".

Thanks everyone, yes she was in her 70s which was quite old then.
