Every year, many millions of pounds from the Government and research charities are spent on health research. This research has changed our lives; in the UK, our life expectancy is now 20 years longer than it was in the 1930's and many diseases that were often fatal or disabling, can now be prevented or cured. Living longer means we may suffer from illness related to old age, but through more research, conditions such as arthritis and Alzheimers could be prevented or managed better within the next 20 years.
