I agree with @somethingsubtle here. All our political leaders ranging from Justin Trudeau(Yes he is 46) to Donald Trump are elders. It is not the age or gender that has to get respected, but the deeds and attitude! Many people live the same year 80 times and call it a life. Considering the vastness of the entire universe, our lifetime is insignificant even if it is 120 years. From a broader point of view, one should respect (That doesn't mean bow the head) others purely based on their actions. Even 5 year old child is capable of earn respect!
