The Mail has provided a lovely infographic to make you feel inadequate if you haven't done certain things at a certain age: http://www.dailymail.co.uk/femail/article-3087433/Marriage-27-house-29-earning-40-000-year-37-hitting-major-life-milestones-time.html

First kiss: 17
First holiday with friends: 18
[Move out for uni: 18, but i think they mean move out properly]
First full time job: 21

Haven't done any of the others, but hopefully will pass my driving test and buy my first car aged 23. What about you?
