Just saw someone giving chest compressions

I was out to have dinner. When I was looking for what to eat near the billing counter, I heard people shouting. When I went there I saw that a man was lying down unconscious and his wife was shouting to call an ambulance. There was another lady who was giving chest compressions to this man. All this while I kept looking at the unconscious man and mind was racing and I kept thinking what can I do to help. But I couldn’t. It felt like me or anyone being there would just add to the panic. So I was just standing there numb Luckily the unconscious man opened his eyes and seemed ok soon enough. They probably took him to a hospital. I’m really grateful to this lady who took immediate action during the chaotic few minutes. This incident will stay with me for a while, partly because I feel bad to have gone numb during such a situation and partly because it makes me realise how we don’t care enough about our health. I hope that person recovers quickly
