One of the problems people have today is that they are no longer in contact with their own bodies. They don't understand the signals their bodies are giving them. In the long run this can lead to obesity, burn outs, heart attacks and lord knows what. Nothing pretty I assure you. The body doesn't really discriminate between types of stress. Most people can't feel the difference between hunger and thirst. Deadlines can set off the same type of triggers in the brain as an angry bear.
