1. I can cook : Not really
2. I can repair a hole in the wall : Ask me another one
3. I can travel on my own : Yes
4. If ever attacked by someone with a knife, I can (theoretically) disarm them and proceed to mortally wound them : That's not me at all
5. Change a tire : Not any more. There is a fantastically complicated wheel lock system on my car and last time I couldn't figure out how to get the wheel off. I now travel with an instant tyre repair canister in the glove compartment
