It can feel good lounging around and doing nothing,
sometimes it’s too good. Whether it’s to avoid work or escape physical activity
we all have those days. But then again why are some people way lazier than
others? Is there any gene that causes lazy behavior?
Evolution has molded our brains and bodies to respond
positively to natural rewards such as food, sex and even exercise. The pleasure
we experience during exercise comes largely from DOPA-MINE SYSTEM in our brain which conveys these messages
throughout the body ultimately hoping to ensure the survival of our species.
For many the pleasure to arrive from exercise can become just as addictive as
food and sex. But we are all up for food and sex many struggle with the desire
for physical activity even though it’s in the central part of human biology.
Scientist’s studying mice have found an interesting genetic
connection after separating mice into two groups those that chose to run on
their wheel more often and those who decided to not run as much. The difference
was clear in their offspring. After generations the running mice would run on
their wheels 75% more often than the other group and by 16 generations they
were running 7 miles a day as supposed to the average 4 miles. It seems their
motivation for physical activity was genetic.
We all inherit genes from our parents that play key role in
the development of our brains and these genes can make some literally crave movement.
In fact the brains of the running mice had larger DOPA-MINE SYSTEM and regions that deals with passion and reward.
They required activity otherwise their brains will react similar to a drug
addicted person. They were genetically addicted to running.
We also inherit genes responsible for our other traits from
impulsivity to procrastination to work ethic and straight up laziness and it
turns out our physical laziness may be linked to the gene. This gene is
responsible for a type of DOPA-MINE RECEPTOR,
without it you are more likely to fancy sitting around and simple doing less
than those who have the properly functioning gene.
So the truth is your desire for activity may not be entirely
up to you but many environmental factors also apply which means you are not
doomed to art of laziness although making a change will be harder for some. Awareness
in terms of Knowledge is power so if you think you are genetically lazy get off
the couch and fight your DNA.
Your brain will reward you in the end.
