You seriously want data to show that taking exercise throughout your life (and cycling is excellent in that respect for many reasons) means you will live a longer and healthier life and won’t spend their final years in a decrepit, immobile state?
Sorry but I thought that sort of thing was common knowledge.
Whatever health authorities try and do in the way of publishing ways to live a healthy lifestyle seems to fall on deaf ears.
If I said that smoking caused lung cancer, you you be asking for data for that too?
You should read up on the Caerphilly Cohort study where they studied and are still studying) a whole town of 2235 men since 1979.
They chose men rather than a mix of women and men so they could rule out pregnancy effects and the fact that men had more heart problems than women).
The Cardiff University study found factors including diet and not smoking had an impact on preventing illnesses developing in older age.
However exercise had the single biggest influence on dementia levels.
They also had 70% fewer instances of diabetes, heart disease and stroke, compared with people who followed none of the factors.
The size of reduction in the instance of disease owing to these simple healthy steps has really amazed us and is of enormous importance in an ageing population," he said.

What has surprised the scientists conducting the study is that although all the evidence is available:
The adoption of a healthy lifestyle by men was low and appears not to have changed during the subsequent 30 years, with under 1% of men following all five of the behaviours and 5% reporting four or more in 1979 and in 2009.
I mentioned cycling specifically as, for older people, it’s still possible to take a hour or two of really good and useful exercise on a bike without too much stress on the knees and other joints. I saw an interview with some of the men on the trial and they had been on a bike ride and were chatting, laughing and incredibly coherent in their speech-they could have been teenagers (apart from the coherent speech). They were in their eighties.
