Answer:
Senior citizens must be respected as they have already contributed enough for the sake of upcoming young generations.
Step-by-step explanation:
Senior citizens getting respect as well as having few facilities ahead of many people might be a way to show our gratitude to them as they have already worked hard enough when they were young for the sake of this new generation. Ageing is a natural process; every person requires care at this moment of his life as they're already low on energy and need to be helped and taken care of by their children and other people. So helping a senior citizen at times could result in your well-being as only if you're kind to others, the others would be kind to you.
