What do you think of making a will?

I know that normally people will make a will when they are over 60 or if they are ill they will do it as soon as they know what they might have and there are others that never do a will. My dad is around 54 years old and he has been talking about making his will for a long time now I think that it has been around 7 years. The thing about his will is that he want to give everything before he dies but he made a will just in case he those not give what he has to us. I got a call yesterday from one of my brother because my dad told him what he had in mind to give to each of us and he want to give me an idea. I don’t know why but I think that is sad to know that he is giving his hard earned lands and things I hope that he is ok and that he would last 50 more years because I rather have him around even if we don’t talk that much. My dad has always been a hard shell person and when it came to money he would hardly ever give any since he was or is cheap. I do love him even if he was not there all the time since like I wrote before he has a hard shell but I am sure that he has a big heart but he was hurt in life. I am scared to know that there might be something wrong with him and that might be the reason that he is giving his things. I am not sure that if I might get something since what he has is lands for farming and I have no idea what ells. I am so upset about it that I know that I wont be able to take anything from him because it is sad I just hope that it is not true that he is doing that I rather have him sale it and keep the money so he can have a relaxed time going on vacations or what ever he wants. So my questions to you are, would you make a will? Would you have it read until you die?
