What are some of your favorite life hacks?

In the past I was an Army Diver and our team had a doctor. Anytime we dove the tropics the doctor had us place two drops of h2o2 in our ears before and after every dive. There are some very nasty bacteria in tropical waters.

Divers have to clear their ears when diving or possible ear drum rupture. We also used it before flights that helps to equalize the pressure in your ears.

Thing was other teams of divers had moderate to severe infected inner ears than our team. Matter of fact I can't recall anyone on our team ever having an infected ear.

What is the mission of Army Divers?

After active duty with the Navy I hired on as a civilian employee with Naval Avionics. One 10 year stretch I performed overhaul and repair on underwater ordinance locators (metal detectors) that Navy Divers used mainly to find mines.
