Usually when something offends one's olfactory senses, it tends to absorb it and then forget about it, allowing the person to function despite the existence of the offending odor. However, I find that Angiospermae tend to be a special case particularly in their processed form. Their odor has a more lasting effect on the olfactory senses leading to a sensation of the scent "coming and going". The irritation induced by them follows quite naturally from this effect so I won't spend any time discussing that. However, irriation to the olfactory senses in general is a topic worthy of examination. Can this affect typing rates? The answer is most definitely yes. The olfactory senses is one of the strongest links to memory and as we are all aware, reminiscing tends to lead to decreased productivity. Reduced productivity would without a doubt translate to being a biological inhibitor of typing rates.
