Have you ever wondered how someone could live to be over 100 and wanted to know their secret? Well, according to science the secret to longevity is not always being a health and exercise freak but you are born with it. Scientists study the DNA threads of humans as the DNA contains your genes that makes up who you are. Some studies show how at the end of a chromosome is a telomere that protects the chromosome. Scientists have connected the size of the telomere to the longevity because every time a cell divides the telomere gets shorter and they found a connection that the longer the telomere the longer you are expected to live. 
Other scientists looked at the marker in the genes in people older than 90 and found genetic markers being similar amongst them. They had had a theory that people tend to live longer because within their genes they have less markers associated with diseases but that has not been proven. Looking at genetics to determine longevity seems more logical because longevity is not something you can predict from your parents or grandparents traits. Do not get me wrong, exercise and how you eat play a role in your life as well, because negative connotations in your life like stress, smoking, excessively drinking, and violence can definitely make your life span significantly shorter. Little things like eating right, exercising, medical care, and the environment you live in could also influence your body to live longer. Even if you are not born with it, taking care of your body and mind in the long run will surely pay off in living longer than someone that excessively drinks, smokes, and does not eat healthy. As of right now, some of these things may not be on you mind because I know for myself eating healthy is the last thing on my list, but as you get older these things become a priority as these little changes in your life can be the road to living until your 100 or until your 60.

Very interesting blog! My great grandma lived until she was 97 and I always wondered how she did it. I would have liked to see more information on the blog to reveal some of the secrets, but I loved the topic.
This is a very interesting blog topic. I honestly thought that living over 100 years old was due to how you treated your body all though our lives. It is very interesting that genetics do play a role in how long we live. According to Health Magazine, another way that we can control how long we live is to not over eat. At St. Louis University there was a study that confirmed that if you eat less, you age slower. Also, they confirmed that in 2008, limiting calories confirmed lowering the production of T3, or the thyroid hormone that slows down metabolism and also speeds up the aging process.

This topic is really interesting but you didn’t really have any data to back up your points. It makes sense for genetics to predict lifespan, or at least affect it in some ways, since they also affect many other aspects of our lives. However, after doing some research, I found out that this paper presenting the claim that genetics predict lifespan was retracted due to inaccuracies in the data. If you want to learn more about this, check this article out!
Your points are interesting, but I believe you could have created a much better post when going in detail about how genetics could be rearrange to enhance the life expectance rate. You do not really backup your information with details and statistics.
This blog has great potential, but if you expanded on your ideas then it would be much better. You need to add a study that explains research done that shows us evidence living longer can be due to purely genetics. I also think that exercising can help you extend your life.
