do you enjoy running?
I never did before l liked walking but for my fitness I did look into running. It is described as the worlds most accessible sport.
my dad and my niece both really enjoy it.  I haven't been able to do it b/c it is really hard impact sport and i have a bad back
It is such a contrast to walking where one foot is always in contact to the ground and legs are kept mostly straight.  What sports are good for you to do with your bad back?
low impact sports such as biking or swimming
-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
It is assumed that the ancestors of humankind developed the ability to run for long distances about 2.6 million years ago, probably in order to hunt animals. Competitive running grew out of religious festivals in various areas. Records of competitive racing date back to the Tailteann Games in Ireland
it's a ballad. It's hard to do but I'm glad I did. I got pushed into it by Inflo really. We'd been talking about it all day and I was telling him about my dad and he just said you should write a letter to him. And I didn't really want to because it's a bit cheesy, but from there... the song came of it. I think it's really beautiful. I dunno why at that point I decided to let that happen," Pritchard
