Finally the answer to the question How to live a long life? has been found. At least that s what it seems from a recent research. There's a multi-billion-dollar industry devoted to products that fight signs of aging but moisturizers only go skin deep. Aging occurs deeper at a cellular level and scientists have found that eating less can slow this cellular process. Recent research published in Molecular and Cellular Proteomics offers one glimpse into how cutting calories impacts aging inside a cell. The researchers found that when ribosomes the cell's protein makers slow down the aging process slows too.
