Stress hormones accelerate the breakdown of telomerase - a coating protecting chromosomes - in mammals.
An excess of stress hormones causes the body to shut down non-essential functions - including the immune system. This is an explanation of why ulcers, caused by bacteria carried by two-thirds of the world population, occur in some cases but not in all.
Stress and excess body fat also kills brain function. Neurons are less likely to fire while the body is under chronic stress.
Relax, kick back, and then do some serious work.
