Symptoms - For those who push themselves past the point of exhaustion.
The Oak type will battle on regardless of how great the odds seem. They are the plodders who say the job must be done. They resent things such as sickness that will interfere with their work. They rarely ever give up, though they will often become depressed by the seemingly insurmountable odds.
Taking Oak helps by giving them great endurance, strength and commonsense and the ability to handle stress.
It's not unusual for people to push themselves past their limits, especially when they feel they are the only ones who will do or can do the job they are doing. One of the danger signs that one is at this state is that you feel as though that even taking holidays will not change the way you feel.
