【英语时差8,16】手上细菌

Ya?l: Y'know Don, you've been doing A Moment of Science for a long time now, getting science knowledge out to the public, you deserve¹ a handshake. Don: Uh, no thanks, Ya?l. Y: Why not? D: Well, it's nothing personal, but there're lots of different kinds of bacteria on women's hands. Y: But that's not fair! Men's hands have bacteria, too. D: True, but not as many different types as women's hands. Scientists at the University of Colorado found that women's hands, especially, are just teeming² with all kinds of bacteria. They're not sure why this is the case. It could be because the moisture³ on mens' hands is typically more acidic, and bacteria don't do as well in an acidic environment. In any case, the bottom line is that we have a lot of bacteria on our hands--at least over a hundred different types. Y: Wow! But are all these bacteria a problem? Are women's hands somehow less healthy or hygienic? D: Probably not. Just like we have lots of useful bacteria in our guts⁴, the bacteria on our hands are probably there for a reason. Or, at least, they're not doing us much or any harm. Some bacteria actually prevent the spread of harmful microbes. Y: So, should we be washing with anti-bacterial soap? D: It doesn't seem to hurt. The scientists found that hand washing doesn't really change the diversity of bacteria on hands. Anti-bacterial soap kills most bacteria, but they soon return. Y: So will you shake my hand? D: Sure. Put 'er there.
