“I Went Skydiving at 84!”

As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of a woman to do that. I got a taste of that dream in 2011,when my husband arranged for me me ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time ,I told my husband that I wanted to skydive. So when our retirement community（社区）announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.

In the essay, I wrote about my desire to skydive, stating George Brush Sr. did it at age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that I was one of the winners. I just couldn’t believe it.

One june 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn’t frightened—I was really just looking forward to the experience. When we reachen 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute（降落伞）, then we just floated downward fo zhout five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt—much better than the hot air ballon. I was just enjoying it.

Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don’t stop living just because you are 84 years old. If there’s something you want to experience, look into it. If it’s something that is possible, make it happen.
