Nothing unusual to give a cause of death as 'old age' . Many very elderly people when they go, just drift down and then shut their eyes and never open them again and 'died of old age' is quite a commonly given as the cause of death in such cases.
Why cannot people just accept things at face value when someone is given a perfectly normal cause of death at the age they died at.
Your next holiday must be to where the first holiday you remember , where are you going?g
