A tracheostomy provides an air passage to help you breathe when the usual route for breathing is somehow obstructed or impaired. A tracheostomy is often needed when health problems require long-term use of a machine to help you breathe. In rare cases, an emergency tracheotomy is performed when your airway is suddenly blocked, such as after a traumatic injury to your face or neck.
It's important that a child get's there vision checked to see if they have any problem's that could effect there vision, of have a bad effect on there eyes. Thee could also be a chance that the child may need eye surgery, but won't know because they haven't gotten there eyes checked.
If children don't gey there eyes check serious problems may occur. For example: Blindness, and many more health problems. The main rick is a child going blind, or even having to loose there eye. Aything can ouccur in eyes, which could have bad effects on there eyes.
When you live with children, you influence them everyday
One way you can get Asthma is for example either working in a heavy industrial place ( like a coal refinery) or living in a place that has very high pollution you would usually develop it at a young age. Type II diabetes you usually develop either from it already been in your family blood line. Or from eating very fatty foods from a young age. Or just being very overweight for a long amount of time. You can develop Cancer from working in heavily radiated workplaces without proper protection. You can even get it if you have something in your genes that just makes you more susceptible. And you can get Cardiovascular Disease from eating to much red meat or too much fat filled food. Or not being physically fit ( don't need to be overweight). Sorry can't help you with Osteoarthritis.
Hope this helps!

Well basically, the Sun is pretty much our energy source. Without the Sun alot of the living organisms that roam here on Earth would probably perish, that is including humans. Without the Sun, there would still be science, just alot of it narrowed down to few pieces of information. The Sun is what provides any heat at all, or any oxygen. Or alot of things here on Earth. So the answer is true, the Sun is the heat source for convection currents anywhere. :)
