Taking swabs from from the facial fuzz of 18 men and necks of some 30 dogs of various breeds, the researchers from the Hirslanden Clinic in Switzerland found out that the beards were dirtier, and the dogs cleaner.
Every single bearded men, aged from 18 to 76, had high counts of bacteria in their beards. While only 23 out of the 30 dogs had the same result. The other dogs tested recorded medium to low levels.
Seven of the men had so much beard bacteria, there was a risk of them getting sick.
Researchers actually found this disgusting information out by mistake, they were trying to find out if men could pick up dog diseases in their facial hair.
Looks like it’s high time to shave.
