It is hardly believable but the ability to laugh is only quality which distinguishes us from animals. Laughter is a real benefit. It is even said that it heal body and soul. There is much truth in that.
Laughter helps relieve the stresses of everyday life, smooths away tiredness and depression, allevites suffering and ensures sound sleep. It is also the best means to prevent illnesses as it speeds up the process of metabolism, stirs up the circulation of the blood, strengthens the defensive functions of the body and, as a result, builds up the system.
Apart from its therapeutic effect, laughter plays a very important role in human relationships. It is commonly known that people who often laugh are more successful in life. Why? The answer is simple. Firstly, thery make friends more easily than ill-humoour fellows. Secondly, they never take themselves too seriously and this helps them maintain mental balance. Thirdly, they are being employed more easily than non-smiling workers. The reason is that they achieve better results at work: a cheerful shop-assistant sells more goods and a buoyant manager concludes more contracts for his company.
It has been proved that people who like laughing are self-confident, tolerant and more willing to accept other people's weaknesses. It is so because laughing purfies the emotions and helps get rid of aggressiveness. If we do not try to relieve tension, it finally turns against us: we either fly into a rage and worsen our relationships with other people or we restrain our emotions and drive ourselves to a breakdown. Therefore, instead of damping other people's spirits or bringing a disease on ourselves we should burst out laughing as frequently as possible. Even 'dying' with laughter does not harm anyone. Neither has it any side effects. On the contrary, it is the key to happiness.
