What did you weigh when you were 18?

When meeting with the trainer guy today he asked me what I weighed when I was around 18 to 20 years old. Apparently the size you were at this age is where your body settled into for your bone structure and fat cell count. So that's a weight you should be aiming toward if you were at a healthy size back then. I've heard this before so it wasn't a big surprise. But the problem is... I have no clue what the answer is. Throughout my life I don't remember milestone weights like so many people do. I don't even remember weighing myself all that often when I was growing up or in young adulthood. It just wasn't a focus for me, I guess. So I'm going to try and dig through some old stuff and see if I can find any where that I might have recorded my weight. I know I have a memory book type thing from my senior year in high school, so it might be in there. I have my college paperwork, so I wonder if there was ever a place I needed to write my weight down on anything. I suppose I could see if I can get my medical records from back in those days, but I'm not sure if they are even available anymore. The only weight I clearly remember is when I hit 250 and I kind of freaked out. I don't remember which year, but I know I went on a big-time diet and exercise binge to try and lose some weight. But other than that I don't really remember anything. Do you know what you weighed when you were 18 to 20? Or do you just remember certain weights you were at at different times in your life (graduation, marriage, pregnancy, etc.)? ~Pam
