• J. Timothy Lightfoot thinks that genetics can determine if a person is lazy or not.
• He cross bred active and inactive mice and found heredity is within 50% of mice that are active.
• He found that active-promoting genes dominate traits in 75% of the exercises mice love.
• Genes can control muscles differently so they are capable of burning more energy and reducing fatigue.
• There is a discovery that there is an inherited drive to being active or not and a hypothesis has been drawn up that chemicals in the brain are responsible for it.
• This relates to our genetics units because we discuss of how the activation of a gene can do something different in the body even if there is the same DNA.
  

I think that genes play a role in being active or not. However, for humans there are other factors that can determine laziness. Technology dominates our generation with computers, TV, video games, and the result is lack of or no exercise at all. The environment affects all of us and if we were once active and stop because of the exposure to technology, then that does not really prove that genes control laziness. Our mindset can change as well by deciding to be active or not. If we are lazy and there is prom coming up, then it is possible to make up your mind to get in shape, and that is not decided by genes. This article is thinking outside of the box and genes may affect our activeness to a certain degree. However I do think that other factors can determine laziness more than genes.
