After wearing jeans without washing for 15 months they receive the same amount of bacteria, as well as after 13 days of wearing

Canadian student Josh Lee did the "dirty work" for his professors in college, engaged in the research of bacteria on the fabric. Josh was wearing the same jeans for over a year and put them on during this time 330 times. If the jeans fell any dirt, it cleans them with paper towels, and left for the night on the street or in the freezer to get rid of the smell.

After 15 months and 1 week of wearing jeans on the professor checked the content of bacteria. Then they were finally washed, and Josh began again to walk in them. After 13 days (mean time to wear jeans on laundry before washing, according to statistics), were again measured. It was found that the number of bacteria in both cases are not significantly different.
