People measure age by birthdays and anniversaries, by calendars and changes in appearance. But though we typically consider age to be the amount of time a person has been alive, that does necessarily not account for the biological and mental changes a person experiences as their life progresses. Different lifestyle habits and environmental factors, such as diet and exposure to chemicals, can have an effect on your body, and the experiences you go through have an effect on your mentality. Not to mention, genetics also plays a role in how you age. Therefore, here are 9 ways to know your body’s “real” age.
1) Length of Your Telomeres
One means of discovering your biological age is to find out the length of your telomeres. This can be done with a simple blood test. Telomeres are segments of DNA found at the ends of each of your chromosomes. They do not encode proteins like most genes in DNA do, but rather serve a protective role. Whenever the cells in your body divide, the chromosomes need to replicate, and when they do so, they get shorter each time at the ends. Thus, the presence of telomeres prevents the loss of DNA that contains genes necessary for life. Since telomeres shorten as you grow, their length can be used as a measure of age. The shortening of telomeres has been associated with medical problems such as decreasing bone density. This is because when they become too short, the DNA cannot function properly. You can find out your telomere lengths using tests such as TeloYears.
