The longer our parents lived, the longer we are likely to live ourselves, and the more likely we are to stay healthy in our sixties and seventies. Having longer-lived parents means we have with much lower rates of a range of heart conditions and some cancers.
The major study, funded by the Medical Research Council and involving almost 190,000 participants in the UK Biobank, is the largest of its kind. It found that our chances of survival increased by 17 per cent for each decade that at least one parent lives beyond the age of 70.
