This is average life expectancy of a human being on earth. Keep in mind that this graph is an approximate number, it depends where you live in world and what your lifestyle is like. So we all are born and that is at the beginning of this graph, each of lines represents 10 years of your life. You of-course can live longer than 80 years or live shorter life than 80 years, you don't relay know you can die at 30, 40. Now think about the time you have on this planet: We all are born then we hit our teenage years, and roughly around age of 20 we start to work and we work all to we are around 65. As you can see most of our life we are working, and it is very important to do something that you love, because it takes most of your life. Being kid is nice, you don't need to worry about anything, and being old is nice because you can focus on your hobbies not worrying about going to work. But actually the years in between are majority of our life, and we shouldn't be worrying about retirement during these years, but instead be happy about our work and the things that we are doing. If you are working job that you hate, just for a paycheck, then you need to make change in your life. Because one thing is certain we all live on this world a short period of time and we all die it is inevitable. You only get one chance in this life, so go on and do things you love.
