God is in control of your quantity of life. But you are in some control of your quality of life. Therefore, do your best to avoid physical, mental and financial decline by working out daily, reading and writing every day, and investing consistently. You become better at what you do regularly. And you lose touch when you stop doing them. Of course, no one lives forever. But the difference between enjoying your old age and enduring it is down to your daily habits. Start a healthy routine now when you still have your youth, so that when you are elderly, that routine can power your life like a machine.
