Do we all have the will power?

I have seen it happen twice within a span of 1 month...my patients were doing ok, not too bad, but ok...able to sit out in the chair and talk a little...no doubt a little grumpy at times, as most patients are anywayz....then when the doctor speaks to them about their illness, their prognosis which is not optimistic, the vicious cycle begins from that point...they start looking tired and empty sometimes....they begin to lose the spirit and just 5 days, a time of merely less than a week, they are gone....at least physically no longer on this earth...it's scary...how important the human will power and spirit is....that's probably why sometimes certain people can live longer than expected and survive illnesses...it's the will power, i guess......Will I have it? if I know I may go soon, will I have the will I used to think I have....i have no answers to this....sigh~....all i can say is that i will do my best for all of you around me....tanks pple....**
