My job qualifications

Andrew has an assignment in which he has to research the requirements of three different career choices. He has a web site which lists many of them. One category are the purely physical demands. He tells me in order to do my job a person must be able to:

1. Sit at a desk for several hours at a time.
2. Stand in front of a class.
3. Speak clearly so that people can understand.
4. Focus on objects a short distance away.

I think I can do all that...most days.
