If you are involved in any sort of physical activity, there's a great chance that you will need to get cleared with a doctor—especially if it's a full-contact sport. Whether you are in an adult intramural league or practice martial arts like jiu-jitsu or muay Thai, you will need to reach out to a doctor that can give you a sports physical. By touching base with them well in advance, you'll be able to get the help that you need in order to go through the physical and pass it with flying colors.
As your parents grow older, it's perfectly natural to be concerned about them. The roles often reverse, with you beginning to show your parents the same level of worry that your parents had for you when you were coming of age. The situation can be a bit more tremulous if your parent happens to live alone. They might seem to be perfectly okay and refrain from expressing their need for care.
