From this video, we can know that women's hands have 40% more species of bacteria than men's hand and the possible reason is because of the sweat on men's hands can be more exsiccated than women's hands. Furthermore, the researchers found out that there is one hand has over 100 bacteria than we thought and there are 13% of bacteria in common to all people's hands, it means a lot of variety of bacteria in our world and even our hands are the same body but they still have diffent types of bacteria on one hand and the other.
- I was very suprised when I saw this video. Because right now, maybe on my hands, there are a lot of bacteria, it makes me feel scare of my hands so I think, the best way is, sometimes, wash our hands 3 times, in the morning, afternoon and evening.....=___=
- New words:
- exsiccate (v) : dry up
- Strain (n) : kind, species
