The Buddha, who began with a perfectly wonderful, plentiful and peaceful life as a young heir to a king's throne did not ask what applied to "his" life. He wanted to know what life itself was that it contained suffering as old age, disease, fear and death - for anyone at all. After many years of authentic searching, he famously noted that attachment to the idea of a personality that owns a life is the primary problem leading to suffering. This suffering happens either now or later, but it happens. If you have had no attachment that has led to suffering in your life, then you have no need for the understanding of the Buddha except that you might have compassion for others who do have difficulties. Not all people run into this problem, but most do eventually. Whatever the outcome of life, as it lives you, you always are that profound nature that is often called True Nature or Buddha Nature and which is the ground truth of what you are even while struggling with "your" personality and it's painful desires and aversions. Some day the understanding of the Buddha may help you. He was also called a doctor of the greatest medicine. Good luck.
