Every individual should have a program to detoxify and cleanse the inside of their body. We all know that bacteria and viruses get on our hands and other body parts and that crap has to be removed with hand and body washing. In a similar way, toxins(drug residues, pesticides,carcinogens,etc.) build up in our body fat. You get rid of these poisions through the Digestive, Cardiovascular and Urinary Systems.
There's different detox programs to handle the above. I've went through an intense cleansing regimen that stressed long sauna time, large vitamin doseage, intense physical exercise and oil/mineral supplements. Although this was a tough program to get through, I did get healthy results from it.(The immediate one was a peaceful gentle glow.) However, as the years went by, I found that I could recover quickly from physical diseases and injury. I, also, had the energy to work out regularly in the gym and play sports.
When others look at me, they think that I'm 10 to 15 years younger, than what I am. I attribute part of this to my "detox program" I took over 20 years ago.
There's more than one cleansing method. So check it out and see what's good for you. Good health is something, you work for not something that just happens.
