[Stoves] CO- and Oxygen-affinity to haemoglobine

[Anand Karve]

Dear Andrew,
our bodies do adapt to atmosphere at high altitude. The usual response
is increase in the haemoglobin content of the blood, so that the blood can
absorb more oxygen from the thin air. Therefore, it is not hard to believe
that our bodies also adapt to chronic exposure to relatively high levels of
CO
Yours
