Fear of death is really common. It pushes people to do crazy things in an effort to be as immortal as possible. Our society is fascinated with youth and health. Many commercials seem to be about not looking old, staying young, and fear about things that could possibly go wrong with you.
But what is there, really to fear? We are all going to go some time. I can virtually promise. And… we’re all going to get old, and most likely, look old. I’ve seen people who’ve had plastic surgery, and even though their skin and features look young… they still look just about their age. How is that possible?

I guess the only thing I can recommend for the fear of death, is to look at it directly in the face. Are you afraid of death? Read up as much as you can on philosophical or religious books of your choice, NDE’s and other things that relate to it. Don’t back away from your fear, because whether or not you think it affects you, it will. If subconsciously your fears base on a fear of death or growing old, you should face it head on, or you will subconsciously act with those fears in mind.
Since you already know it’s going to happen, why fight it? Learn as much as you can, and then let it go. Fears that don’t serve you, don’t need to exist.
