There is a clichéd and outmoded notion that as we grow older we get more rigid in our beliefs and ways of viewing the world. As a teenager I enthusiastically embraced the slogan that you couldn't trust anyone over the age of 30. Now, I am more certain about the importance of moderation and healthy lifestyle, yet less certain about many practises and beliefs – nutritional and spiritual – I used to take on board. However, as I get older I have started to realise that the strength of my beliefs is often more down to cycles or phases I am going through, rather than a strictly linear chronological progression.
