I visited the region around Dharamshala last year which is the same altitude (1500m) and was somewhat surprised I did not notice any effects of the altitude. My whole life (nearly 40) I've been living at sea level, except for trips.

I've lived mostly outside cities though so no major pollution. I'd imagine for Delhi folks the pollution must have a big effect on their lungs - but you'd think it would translate to working well for high altitude.
