PREVENTION IS BETTER THAN CURE

It goes without saying that the PREVENTION of ailments and illnesses, is BETTER than having to try to CURE ailments and illnesses.

There are some steps that you can take YOURSELF, to try to prevent the onset of ailments and illnesses.
I am sure that you are already familiar with these measures, but I am just here to remind YOU.

Be mindful of what you eat...
Try not to drink in excess...
Try not to smoke... I don't know of any health benefits of smoking cigarettes at all, whereas it can be argued that an odd glass of wine, for example, can benefit the health.

Try to do something by the way of exercise on a regular basis. By this I don't mean that you have to overdo exercise, or become obsessive about exercise, or even sign up for expensive gyms!
It could just be a stroll around a park.
HIPPOCRATES apparently said 'Walking is man's best medicine'.
There are many different forms of exercise from the gentleness of yoga or tai chi to the more strenuous exercise of, say, kick boxing.
When it comes to exercise, you need to find something that suits YOU. It may not be something that all your friends are doing, but that's OK.
Try to look for ideas on the internet, if you are stuck, or seek out a fitness instructor, if you really feel you need a bit of guidance on the matter.
Remember, this is about YOUR life, and YOUR health.
GOOD LUCK!

P.S The NHS now has information on the internet regarding diet, exercise, and quitting smoking!
