In space, you need to exercise your heart since it's not pumping blood around at the same rate.
Interpretation
Exercise is crucial in space to maintain heart health due to different blood circulation dynamics.
Mae Jemison emphasizes the importance of exercising the heart while in space, highlighting how the unique environment affects blood circulation. In space, the absence of gravity alters how blood flows in the body, making regular exercise essential to ensure continued cardiovascular health and to prevent potential complications for astronauts.
In practice
In a speech about the importance of health for astronauts, this quote can inspire future space explorers.

We have to have a combination of general relativity that describes the warping of space and time, and quantum physics, which describes the uncertainties in that warping and how they change.
Q: What were you thinking when your colleagues were out there making cosmic history? A: I just kept reminding myself that every single component in this spacecraft was provided by the guy who submitted the cheapest tender.
In science, you can say things that seem crazy, but in the long run, they can turn out to be right. We can get really good evidence, and in the end, the community will come around.
