At least National Rail keeps you feeling like a 'Young Person' until you're 25. If entitled to a five year free railcard with your student bank account, don't forget to apply for it. That would make you feel very silly and possibly drive you to write an article yearning the mistake. No sympathy expected.
Every August I spend a week or so in Oxfordshire visiting my in-laws, who live in a sweet little village six miles outside of Oxford. While we are there, we take long walks in the countryside, have lunch by the river and barbeques in the evening, spending time with our five year old nephew who we don't see enough of.
