I lived in the UK and I owned a home there for a few years in the 1980s. At that time, one topic of public debate was their health care system. At that time it was decided that 70 years of age was the cut-off for life-extending medical treatments. Beyond 70yo a person was expected to die gracefully 'with dignity'. Mike Jagger is 75.
Unless they have changed the healthcare system in the UK, at 75yo you would expect unlimited pain meds for 'care and comfort' only, but no heart surgery or organ transplants.
