I’m part of the Geriatric Federation.

When I was 5, I was a card carrying member of The Six Million Dollar Man Fan Club, and he was an astronaut. So, yes.

Can honestly say no

I tried, but they told me I was not using the actual
Meaning of “space cadet.”

No, but for a time I was the senate.

I tried but I couldn't get my fingers to separate in the middle like Spock's and they left me here on this miserable planet.

No, and you can't prove that I am.

Never any form of "Federation".

If it doesn't have democracy in it you can have your galactic state run government and shove it.
