Liver, spleen, kidneys - 300-500 days and we have a completely new liver, there is no cell of these organs that, for example, heard my conversation with you.After 500 days, all cells will be new.Intestinal epithelium - cells live only 5 days, so it is very important not to indulge in hunger strikes and not torture your intestinal epithelium.Those.We have a constantly renewable body, and only our behavior in this body determines what biological age we will have.I know for sure that at any age you can have a biological age of 25 years.You can learn, stabilize the result and pass it on to inheritance.Your children are watching you now as you grow old.Your grandchildren are now watching you as you walk, and then you will be an excuse for them: “My mother had such diseases... And my grandmother had type 2 diabetes.”You will be an excuse for your children's illnesses if you don't take charge of yourself now.If you don’t want to do it for yourself, do it for your children and grandchildren.Because there is no old age!
