[1]I don't know about you, but I look a lot older than I really am. Now I know I could solve much of that by coloring my hair with some product like "Just for Men", but I refuse to go there just yet. But it really gets upsetting sometimes. For example, at my brother's wedding four years ago, the photographer thought I was his father. Really, I'm not kidding.
[2]And just a few weeks ago, I was a riding in a car with another one of my brothers when he stopped to pick up his paycheck. Anyway, his boss saw me in the car and asked him if _________________. Now, he only saw me from a distance, but it still hurt. Again, I'm not making this up.
[3]So I've decided to fight this battle in my own way. Since I obviously look old, I'm going to act young to compensate(弥补) for it. So what I am doing to act young? Well, it all has to with the way I move around.
[4]First, I try to walk faster than everyone else. That one is not a big deal for me, as I've always had a tendency to walk fast. It's a family trait（特性）.
[5]Second, I try to use quick movements. That means getting up from a sitting position quickly, sitting down quickly, lying down quickly, getting up from a lying position quickly, changing directions quickly, turning quickly, etc. Now this one presents a little more of a challenge to me. I have to be careful not to hurt or damage a sensitive body part.
[6]Of course, if all of that doesn’t work, there’s always the “Just for Men.”
