How you know you are an adult

Today, I went down to the legal office and signed my will. It was really easy, but a bit nerve wracking when you realize you have an official document that gives away your decision making etc should incapacitation etc occur. It is kind of a mortality check. Really good to have one, but it definitely makes you look at death. The lawyer who signed it had a bit of a hand tremor too. Hopefully he wasn't nervous too.
