This is a non-sequitur, I am afraid. On the 108 bus (single-decker) this morning, young woman sitting on the back seat started to have what looked like an asthma attack. Unfortunately, she was doing it very quietly and at first, I think, other passengers thought that she was just being wierd (this *is* London). I became aware of the crisis when two passengers suddenly rushed forward to alert the bus driver, and I looked round to see that the young woman's lips were already blue (and her eyes closed). Two men then laid her down on the seat, and someone else summoned an ambulance with her mobile phone. Apart from being able to tell the ambulance exactly where we were stopped (in Blackheath Village), I felt a bit useless (I am a first-aider but there was very little room at the back of the bus, and two people already doing what they could for the young woman) so I disembarked. The ambulance was still in attendance, with the stationary bus, some 20 minutes later: is that a good or a bad sign? (I mean, it had not taken its patient away to hospital.) I thought, also, that perhaps she should not have been laid down, if she was having trouble breathing.
