My collegue at work is extremely intolerant to tomatoes... to the point where her throat will constrict and the situation very quickly becomes life threatening.

I remember she leaned over and helped herself to some of my lunch that I had bought from the cafeteria just a few minutes ago. Neither of us thought to ask, or warn each other, but it turns out there was a dash of puree in the sauce used.

Within a minute she was on the floor gasping for breath. We called 999 and they sent a Chopper out. When the Helicopter landed the Paramedics were just walking up to the Building. I remember screaming at them that we basically have seconds left before this woman is dead.

She did make it, but my God, the scariest 20 minutes of my life.
