I can't eat tomato sauce. Can't even touch it.
The only bit of DIY I can do is the first bit where you find the phone number of the relevant expert. Can't even call them because I can't explain what needs doing!
I can't sleep when flying. I'm famous for falling asleep immediately after landing, but never before.
I can't read when in a moving vehicle on the road. Trains and planes fine, but not even on a coach.
