What is the 120 rule in diving?
Subtract the depth you’re diving (in feet) from 120. The resulting number is the maximum amount of minutes you should spend at that depth. That is why it is recommended to make a safety stop at 15 feet/ 5 meters, as it gives extra time for your body to discharge excess nitrogen that got dispersed in your system during the dive. Maximizing the time to pause and regain control can help a diver sustain a safe ascent rate.The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (131 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.Age doesn’t limit your ability to scuba dive as long as you’re in good health and comfortable in the water. Many divers in their 70s, 80s, and beyond enjoy diving regularly. Maintaining a routine that includes strength, flexibility, and cardio will keep you in great shape for diving.In the underwater world of scuba diving, descending to depths up to 40 meters (130 feet) is considered recreational scuba.
What is the golden rule of diving?

If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls. The first rule of scuba diving is to breathe continuously and never hold your breath.The only thing for certain is that the optimum breathing strategy when scuba diving is deep slow breathing.

At what age do people stop scuba diving?
As long as you’re in good health and have medical clearance from a dive physician, there’s no age limit to scuba diving. Many people start diving later in life and discover a passion they never knew they had. There is no upper age limit for scuba diving. Many seniors finish the PADI Open Water Diver course (the entry-level course you need to take to become a certified scuba diver) and enjoy diving for years.
