“每次”
用英语怎么说？

Private $20,000 health clinics offering genome sequencing and full-body scans. Gyms with $40,000 annual fees. Blood plasma exchanges for $10,000 or more a pop. One-on-one sleep coaching and $300 wearables. Pursuing “longevity” has become an expensive — not to mention time-consuming — hobby. But it doesn’t have to be: Experts say many of the practices that are most likely to extend your life are also the cheapest.

会员年费2万美元的私立诊所提供基因测序和全身扫描服务。年费4万美元的健身房。每次花费1万美元甚至更多的血浆置换。一对一的睡眠辅导和300美元的可穿戴设备。 追求“长寿”已成为一项昂贵的爱好，更不用说还很耗时。但其实并非完全必要：专家表示，许多最有可能延长寿命的做法同时也是成本最低的。
