Young people, where are you?

I always thought that hiking is not only for older people. At least i was not considering it boring as i always liked it. No. I am not old. Coming to Germany made me change my point of view. Everytime i go hiking in some fantastic place where I can have some rest enjoying beautiful weather and the nature the only people i see are retired people. No matter what time it is. No matter how sunny it is. There is no young people. Therefore i cought myself thinking that i might have an old people mentality, since i don’t go to crazy parties anymore. Some things don’t make me laugh anymore, but i would never call myself an old lady. What is that? What young people do? Do they feel obliged to go only to the fancy parties? Hiking is not sexy enough?
