I hope you have a brilliant day and don't spend the entire day working
.Things you can do at 21 (according to http://www.thesite.org):
21+
You can apply to adopt a child.
You can supervise a learner driver (so long as you’ve held a driving licence for the same type of vehicle for three years).
You can apply for a range of licences that would allow you to fly commercial transport aeroplanes, helicopters, gyroplanes and airships.
You can drive lorries over 7.5 tonnes with a trailer (with the appropriate licence), as well as buses and road rollers.
Being able to fly airships would be pretty cool.
