Ethics

What should we ask God ?
I was told by someone that there is a doctor in a hospital who is doing a lot of Knee Replacement surgeries. Around 800 or so in a year to give a picture of the magnitude. You might think what is wrong with it, it must be good infact. But the point of contention lies with the fact that those who are undergoing treatment under him are returning back with problems within 2 years. The normal norm it seems is that it should not be a problem for about 10 years or so. By now, you must be thinking what has it got to do with GOD and what is this from a person who is not a doctor either. Therein lies the point. I was struck with this question when I heard this and asked the person the questions that I am going to put forward to you too. What do you ask GOD for in all your prayers? What should we ask GOD for in all our prayers? If a person is in great need of money asks the GOD for more money is that right? If a business man wants more money, should he ask GOD for more business and thereby earn more money? It so happened that I got the next two questions which I asked the person. Please put your thoughts on this.
1) What should doctors ask GOD?
2) What should a caretaker in a burial ground ask GOD for?

They are also family people, have the same needs and wants as any others. Just that these are easy to highlight the importance of how what we ask GOD should be.
