I have a seemingly dangerous condition called Barrett’s esophagus – mysterious “lesions” around the entrance to my stomach that were discovered by chance (during medical exams for my cosmonaut training). Not much is known about it, but it is probably not a good idea to swim – as I do every morning – with coffee in my stomach.
比如，我就面临过我自己的两难，有切身体验。我身上有种危险的状况，称为巴雷特食道（Barrett’s esophagus）——在我的胃的入口处存在神秘的“病灶”，我（在宇航员体检时）偶尔发现了它。对于这种状况我们知之甚少，但在胃里装满咖啡的时候游泳——我每天早上都处于这样的状态——不是个好主意。但在喝了咖啡后游泳感觉好得多。因此我只有在很累的时候才选择喝咖啡；在其他时候，我选择不喝。
