4、The same study also showed that only some people secrete chemicals through their skin that indicate what blood type they have.

同一项研究还表明，只有一部分人的皮肤可以分泌出某种化学物质，这种物质能够标示出他们的血型。

Some people do not secrete those chemicals at all, making them less likely to be bitten, the lucky bastards.

另一些人则无法分泌这些化学物质，这使得他们更不容易受到蚊虫叮咬——这些该死的幸运儿们！

5、The composition of the microbes on your skin is another factor.

你的皮肤表面微生物的构成是另一影响因素。

We all have a unique and beautiful flora of microbes living on our skin. In fact, we have more microbes on our skin than actual skin cells.

我们每个人的皮肤表面都生活着美丽而独一无二的微生物族群。事实上，我们皮肤上的微生物们甚至比皮肤细胞还多。

We're actually just walking masses of germs. Anyway, the unique composition of our microbes affects how much mosquitos want to bite us.

我们都是巨大的人形自走培养皿。无论如何，每个人独有的微生物构成对有多少蚊子想要咬我们有着不可忽视的影响。

6、Exercising also makes you more appealing.

运动使你变得更“迷蚊”。

This is because exercise increases the amount of lactic acid your skin secretes, as well as increasing your overall body temperature.

因为运动会使你的皮肤分泌更多的乳酸，并令你全身体温升高。

For mosquitoes, this is the equivalent of wafting delicious baked goods and fresh coffee in front of someone who's just rolled out of bed.

相比于那些在床上葛优瘫的人，你在蚊子眼里更像是一块热气腾腾的烤面包配咖啡。
