How do I fake my own death and create a new identity?

Grow a beard

Well you start by getting the paper work from a specialized person. Hard to find by the way. Then you go and get a car and drive as fast as you can off a cliff overlooking the ocean. The car needs a sun roof so you can escape as the car falls. A life vest is recommended to strap to the top of the car. And you will want a sharp knife to cut the string tied to the are through the door to the life vest. You will not have time to putt the life vest on but it's something to hold onto. An alternative is a life vest that airs up when you press a button but you where it like a belt.

Honestly this will only work until they find the car.

I seen on a tv show or movie, people take over an identity of someone around their age who died. Usually there are people who specialize in getting the paperwork and stuff, but it costs a lot of money.

I don't know but when you find out let me know!
