You only have to do a quick online search to discover the benefits of meditation
Regular meditation has been shown to make physical changes to the brain:
Less stress
The amygdala, the gland which produces cortisol, the stress hormone physically shrinks. So regular meditators are physically less capable of stress!
Increased focus
Meditation increases your ability to stay focussed.
Increased contentedness
Through the increased ability to focus on the current task in hand, being in the present moment, rather than thinking of other things while you're doing something, you increase your state of contentedness. You are happier.
Healthier
Like sleep, meditation allows the body to go in to repair mode
