"Hurrah" I thought as I saw the BBC's headline "People aged 65 to 79 'happiest of all', study suggests" - finally a good news story about people of post-retirement age.

However, on reading the story I found something troubling. People aged over 90 who participated in the study did not feel their lives were as worthwhile as their younger counterparts. 

With an increasingly elderly population it is troubling to think that people may cease to value their own worth.
