IV. Conclusion

I tried riding my mountain bike on the trails in the foothills, and after that experience I became convinced that mountain bikes are the key to long life and happiness.

Riding the mountain bike in the foothills, I was suprised to see how many other mountain bikers were seniors. They looked stronger than most young people. Also, when they said hi they seemed so happy.

I rode the mountain bike on a trail heading up towards the hills. When I reached the hills, I walked up the slope for a little bit and then sat down in the shade of a tree. For the rest of the day, even after I went back home, I had more energy and was less stressed.

Biking in the foothills keeps you strong and happy. You will live a long time by doing this activity.
