every year or two

Gullotta says a healthy man should visit the doctor every year or two. For those over 45, it should be at least once a year.

古罗塔认为一名健康的男性应该每一到两年就看一次医生。45岁以上者，应该至少每年看一次。

Oh sure, you can crank out a new version every year or two, trying to get the upgrade revenues, but eventually people will ask: "why fix what ain't broken?"

哦，当然，你可以每一两年攒出一个新版本来，琢磨着再捞点升级的钱。 但最终人们会问：“功能用的好好的，修修补补个啥劲？”

Then, every year or two, inventors working for the company could come up with a slightly improved version of the technology and patent it, and the seventeen-year clock would start over.

然后，每年或每两年，为公司工作的发明人可以带来该技术的轻微改进版本，并申请专利，17年的年限也将由此重新开始计算。
