Is space really the final frontier?
William Shatner has found out afterboldly goingwhere no 90-year-old has gone before.
Arent we all adorbs!
Funk was one of theMercury 13women who qualified for spaceflight in the 1960s but never flew.

In just a few days in space,the human body starts to adapt.
A 90-year-old person with normal age-related health changes might arrive in space with their muscles and bones already deconditioned.
This could present additional risks as their body adapts further when deprived of gravity.
Anyone like Shatner who only spends a few minutes in microgravity wont need to worry about this too much.
This would lead them toexperience an acceleration or g-force of 3g.
During re-entry into the atmosphere, the g-forcereaches 6g.
High g-forces can have profound effects on the human body.
At high g-forces, blood can be pulled away from the head which can starve the brain of oxygen.
This can occur atas little as 3g.
In trained astronauts, this rapid entry to microgravity often leads tospace sickness.
Older untrained space tourists, who could already havevestibular impairments, may be more susceptible to space sickness.
