A quick note to encourage you to check out a friend of mine's most excellent blog.
Catherine Rickwood is a senior marketing specialist and educator, with expertise in consumer behaviour. Her doctoral thesis looked at consumer behaviour around saving for retirement.
Her blog is dedicated to sharing thinking and research around positive ageing. Catherine's lifestyle is consistent with what she teaches and she's well placed to share her experience as well as research on many aspects of positive living.
Get onto her work early, so that when she's famous, you'll be able to say you've been following her stuff for years!
