     Years ago, as a young morn with two small children, I struggled to keep up with the demands of a busy

life. One day, I woke up feeling so tired that I knew something had to change!

     A friend gave me some Royal Jelly-an amazing substance (物质) from the beehive (蜂房). I was doubtful,

but desperate.., so I tried it! In time, I began to experience renewed energy and vitality (活力) like never

before! Now, over two decades later, I travel all round the country, sharing my life-changing experience. I'm

grateful for the energy to keep up and love to share this wonderful discovery with others.

     Ten years ago, when I was 73, my mind wanted to be busy and useful, but my body didn't. I became tired

and lethargic (无精打采的). That's when my daughter Madeline tried to persuade me to try her special Royal

Jelly. It made such a dramatic (巨大的) difference in her life, so she was sure it could help me too! Hesitating

for 2 days, I gave in. She was right! I no longer felt worn out. I had a new, youthful zest (热情) for life and

I've been OK-thanks to Royal Jelly!

     When my mom Madeline was introduced to Royal Jelly, it affected my life, too! Mom gave me some of her

fantastic Royal Jelly. Boy, things did turn around! I had more energy and stamina (耐力) and was finally able

to keep up with high school and, eventually, college activities. Today, I'm a busy mom in my mid-thirties with

two active boys and a new business! I have enough energy to do it all! I'm glad I took my Mom's advice.
