Have been thinking about aerial transmission of covid and effectiveness of masks.
The other day on my daily exercise a female jogger passed going on opposite direction and I could smell her perfume for a good few seconds after she passed.
This morning on Bakerloo Line, some fella got on a few meters to my left them moved further away, but again I could smell his cologne for quite a few seconds after he boarded the train.
Hopefully this is just because aren't is lighter than covid so just permeated better, but it has added a layer of paranoia that didn't previously exist.
The perfume you can smell will, I am pretty sure, be in the gas phase rather than droplets, much smaller than aerosols containing virus, and as such you would expect the perfume to go straight through the mask.
The mask will definitely be offering you and those around you significant protection, so stick with it and all the other sensible precautions to minimise your risk.

Additionally, the perfume/cologne smells are not coming out of their owners' mouths and noses, as any Covid-carrying droplets/aerosols would be. If you could smell their bad breath or identify the brand of toothpaste, that would be of more concern.
One man, Thomas Midgely Jnr, is responsible through his discoveries and inventions for much of the world's pollution. Single-handedly he developed
1. The CFC marketed as Freon used widely in refrigeration; and 2. The process for adding lead to petrol.
In a fine example of hubris, one of other inventions killed him. He fell victim to polio and developed a pulley system to get himself out of bed. He got tangled up in it and strangled himself to death.

Tres droll and very informative....thanks for sharing
On an historical note, the addition of lead to petrol allowed aeroplane engines to develop more power
In 1939 and early 1940 the new generation of RAF fighters ran on 87 octane fuel. They were outclassed by their German opponents
The USA allowed supply of 100 octane fuel in mid 1940, just in time for the air battle that summer. This new heavily leaded fuel, along with some other developments, allowed the Merlin engines in RAF fighters to match the performance of the German fighter planes
The USA then supplied 150 octane fuel later in the War which further increased engine performance albeit with the risk of the engine melting
I'm not sure that the outcome of the war would have been the same without Mr Midgley's contribution
