Benefits of Leisure and Recreation

As an industry, it offers a variety of related employment and creates billions of dollars in revenue.

There are many civic benefits of leisure and recreation activities. Sports and youth activities offer leadership development for adults and children. Strong communities are built as parks become a hub of community life. Benefits extend to all ages, childhood, youth, young adults, families, and seniors. Both care for environment and wellness through green spaces are enhanced by beauty. This same beauty helps combat stress through the opportunity for mild exercise and mediation upon natural beauty. Wilderness experiences are available in some locations.

Family Bonding

Physical benefits include increased lung capacity from sports participation, plus reducing serum cholesterol and hypertension, increasing bone mass, strengthening the spine, reducing disease, increase in feelings of well being, reduction in stress hormones, improved attitudes and performances, and improved social skills. For childhood development, recreational areas assist in learning, can keep kids off the streets, and enhance their confidence. Studies confirm that physical activity can aid the learning process in children. Sports activities enhance large motor skill development and social skills. Adult leaders offer positive role models to children. Group sports are well known for promoting social support, networking, and developing friendships.

As if all the above is not enough to encourage support of leisure and recreational activities, consider the following additional benefits:

Stress management – the mild stress of leisure activity can reduce overall negative stress by contributing to relaxation.

Self esteem – especially in children and seniors, mild exercise, group activities, and hobbies and crafts will help create positive self images.

Preventative health – regular exercise, physiological benefits from mild exercise, and stress reduction all are made easier by having leisure and recreational activities readily available.

The Significance of Computers in Our Lives

2010; mankind has come a long way since the first discovery of fire a few hundred thousand years ago. Fire used to be a necessity then, now the computer is a necessity for us as we use it in our daily lives.

One way computers help us is in our lives. We use the computer to communicate with people such as web conferencing with friends who are overseas, to look up on information about a particular topic, socialize on social networks such as Facebook or even to do something as simple as sending an email or digital cards to friends and loved ones.

The computer has also managed to change us from reading hard copies of books, magazines and newspapers, to reading online digital documents such as online newspaper articles and e-books.

In education, lecturers are now using PowerPoint to make their lecture slides which are used during their lectures and students are now able to download the lecture slides into their computers and store it as reading documents.

In the working place, paperwork is now slowly converting from manual printing and keeping documents to storing documents in the computer. The problem with paperwork is that it takes up a lot of space and an office has limited space. Moreover, going digital will help the environment as there will be less demand for paper which results in lesser trees being cut down to be made into paper.

However, there have been some issues raised about digital documents. A digital document can be created and edited by anyone, thus this leads to the owner verification problem. It is dangerous in the working environment, because anyone can edit a contract or agreement after it has been signed and used it against the other party. Another problem would be if one accidentally deletes the document, it will be hard to trace the perpetrator and also very hard to retrace the document.
