history: do you enjoy running?
knowledge: Running has been described as the world's most accessible sport.
response: As a bot, I can't run, but I know it's considered the most accessible sport in the world. Do you run?

As a bot, I can't run, but I know it's considered the most accessible sport in the world. Do you run?
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
knowledge: This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.
response: 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
knowledge: A characteristic feature of a running body from the viewpoint of spring-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.
response: Oh, I see. As for running, from a scientific standpoint, it involves converting spring potential energy in your tendons to kinetic energy.

I'm sure that is very true.  Its great for some people who can handle the constant banging on the joints
knowledge: Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis.
response: Yeah. Not to get all nerdy, but I happen to know that muscles are made from embryonic germ cells via a process called myogenesis.
