Everything I read shows that alcohol, smoking, illegal drugs, and lack of sleep will kill your brain cells. That means your skin suffers, your muscles and wounds do not heal the way they should. It would prevent you from gaining muscle after exercise as you would normally. So your mind, your body, and eventually your spirit will suffer as you kill off your own brain cells voluntarily by taking in large quantities of these items.
Most people drink and smoke or take drugs to relax. They often lower your inhibitors and you end up making bad decisions that you would not partake of if you were sober. I for one have never smoked or taken drugs, and I only drank alcohol when I was 17, and after ending up in a police station I gave it up completely. Now I only drink at weddings or new year’s if at all. And if I drink it is only 1 glass of wine, or a mimosa, maybe champagne or one beer.
I have seen proof of how the body deteriorates by watching my classmates people with 5 years older and 5 years younger than me and see how their body changes. Many factors could influence it, but I believe poor nutrition and lack of exercise as well as partying and overusing alcohol, smoking, tobacco, and illegal items like marijuana, or cocaine and worse items, as well as stress, lack of sleep, dehydration, and too much fast food contribute greatly towards the decay of people’s minds and physical body.
If you want to protect your body then at the very least protect your brain cells and cut out the high levels of toxins from alcohol, smoking, and drugs, and not sleeping. I know so many people who sleep less than six hours and often less than 4 hours a day regularly and that is a huge factor in causing fatigue, and memory issues, as well as a body that just starts to break down without proper rest. Minimal sleep also reduces your cognitive function and I can attest to that by doing all-nighters before a college exam, to wake up early and open my exam final blue book to write and drawing almost a complete blank on all the hours of studying and cramming I did the night prior. Now that was a sobering moment for me, when I realized that pulling all-nighters are a major mistake in trying to prepare for an exam when your mind needs to be rested and calm to perform under the pressure and scrutiny of a midterm, a final or a presentation in front of your management team and client base at work. When they describe the “walking dead zombies” in the movies : you don’t want to be that zombie when your team and your family and friends need you to be at your best.
