Remember how we said you won’t care as much as you age, and that’s a good thing? This carefree attitude will help you handle stress better. As things happen, you won’t be as bothered, and can probably just let it go. Something that would cause an emotional response in your 20s may be nothing more but a causal conservation in your 40s. Plus, when serious things do happen, like the loss of a job or a death in the family, you will be ready to cope in a mature way.
Muscular atrophy, or weakening of your muscles, commonly happens as you get older. You can avoid much of that atrophy by going to the gym regularly or getting a daily walk, but some of it occurs in places where you cannot do much about it. Take your throat, for example. You cannot exercise your throat at the gym, and as those muscles weaken, you may begin to experience difficulty swallowing. Your reflexes may have difficulty determining if you are swallowing a solid or a liquid, and you may start experiencing some discomfort when eating and drinking.
Again, this age-related change is more common in women and is heavily associated with hormonal changes around perimenopause. Another reason you may experience a decrease in libido is the mounting stress that tends to build up around the age of forty. You are no longer young and dumb and have to consider things that you may not have realized before. Alternatively, maybe you just have so many responsibilities now that you did not once have that you just lose interest. Stress management can help here and many other age-related health conditions that tend to set in around the age of 40.
