Deoderant testing

On my search on the internet for extra ordinary things around the world, i found out that in the olden days scientists and pharmacologists, tested the deodorants that we now use very closely. They have been doing it for centuries till the found out that technology can be used to test em. Like i said earlier they tested the product very closely. I managed to find a picture which was taken a long time back showing how they tested the products for better smelling fragrances and long lasting ones. Well i even figured out that these people who tested the testers were paid more than the amount which would be given to any EXECUTIVE in any company. These are not just work its dirty work and these people loved doing that. Now the techonology has brought the new computers which could tell the smell of the plant or a flower just by scaning it is available, these people have no jobs left and they are now dentists or doctors or some other useless jobs which they can get hold of. The deodorants which was produced in the old days was effective and no fakes was available.
