How can I know about my last life? I have some ideas but they are not complete.

I have never understood why people are eager to know about their past life? It has no relation to your current life. Suppose you have a fear of flying and some healer (?!) try to explain you through past life regression (?!) that this fear is because of your death in plane crash in past life then will your fear go after knowing that so called fact? Unfortunately ‘No’! To me these are gimmicks played by some chits to earn money. I believe that those who are not satisfied with their current life, because of any problem; will fall into such gimmicks. If you are one of them then try to solve your problem through proper channel then such stupid claims. Sorry, this might sound you harsh but I’m very clear on this.
