For policemen with their hard work, ways must be found to relieve tension. Yoga and meditation can help them a lot. An old friend of mine has worked half his life in law enforcement. How many years I have known him, I constantly see how his work leaves a mark on him. For a while, he even became addicted to alcohol, since my friends and I were able to pull him out of this abyss. Then I told him about meditation, that it can help, he trusted me and now, two years later, he does nothing but relieve the tension during meditation.
