The Neighs Have It Again … Oldest Olympians are Equestrians!

If there is one sweeping generality to be made about cellular biochemistry, it is that everything is connected to everything else. No mechanism operates in isolation, and many areas of interest to aging research that have been studied point by point over the past few decades are all different aspects of the same larger system. This is becoming much more apparent in this age of powerful computers and advanced biotechnology: specialists can get more done with their time, and thus see more of the bigger picture within which their work rests. Today’s example involves muscle aging, the dynamics of muscle stem cell populations, the role of the immune system in regeneration, and the response of muscle cells to exercise and other stresses. These three are all fairly
