I am a clean person, same goes for my sister. And I don't smell bad, same goes for my sister.
My sister constantly talks about her hair. "Should I wash it?" "Should I pull my hair up or leave it down?" Stuff like that.
It wasn't my idea to take this underwater weighing thing. The doctor puts you in a tank (and I didn't have a shower), makes you do certain things of breathing, and you put your head underwater for a few seconds. Not hard at all.
