II can confirm that health and fittness are of high interest as I had an article posted in health and experienced significant feed-back for my level. It looks like people are more and more interested in how to have a healthier life, but to me that is normal. There are a lot of new diseases which even young people do experience and that could be a reason why they what to be more careful with their health. Not to say that the younger generations are more narcissistic and care a lot about their look so they search for ways to improve their look when they do not like it.
