There are two possibilities I can think of:

• Orbit duration can be used to calculate mass
• The diameter of a star or the parallax distance on the sky (in arcseconds) can also be used to evaluate mass

Damaged because of too much mag? Uh. Mag...?

Huh. My recurring biceps pains are the bane of my existence. And I was also refused for a blood donation due to insufficient hemoglobin. I need to try iron supplements.

Oh yeah often. But there's a decent proportion of my dreams where I'm not me; just some sort of fictional my brain made up for that night.

And about 80% of the time, if there's romance in a dream, it's not me. My brain has trouble fathoming a romantic story with me in it and I can't fault it for it.

I don't know how many people think this way, but I once heard a quote: "If in your youth, you don't vote left, you don't have a heart. If when you're older you don't vote right, you don't have a head."

I don't think that quote says anything good or true, but if there are a lot of people who think that way, well...

I think it's related to safety and insurance but I don't really get it.

No, you misunderstand. It's not expert sex change

It's experts ex-chang'e. It's a site for Chinese space program retirees.
