There are many different body types around, and regrettably many are 'round'. But underneath all the padding and designer wear we can put each body into one of three categories.
The three main types:
ectomorphs - thin and wispy
mesomorphs - athletic and muscular
endomorphs - generously rounded or 'stout'
Your basic body type is greatly outside of your control - more to do with DNA, and your childhood lifestyle than anything else. So if you are over 18 and reading this, you are what you are, although you can fine tune what you already have.
Changing your body type
If you're looking to change the shape of your body the basic groundwork is the same.
eat fresh, low fat and healthy food
avoid large amounts of toxins such as alcohol and caffeine
take regular exercise which should include elements of stamina (puffing), strength (grunting) and suppleness (bending)

Alcohol
If you're going somewhere hot, it's important to keep your body hydrated. Alcohol, however, is dehydrating. If you do have a drink, alternate non-alcohol drinks with alcoholic ones.
Drinking at altitude will get you drunk faster. This means your usual limits will be lowered the first few days, so pace yourself.
Above all, think before you drink. A quick pint before sports or activities isn't a good idea. Alcohol combined with swimming, waterskiing and cycling, for example, can result in injury or even death.
Many countries' drink-driving limits are lower than in the CR. In Sweden, for example, the legal limit is 20mg alcohol per 100ml. The punishment in some countries is mandatory imprisonment.
Drugs
Check entry requirements before you book your holiday.
Penalties for drug offences committed abroad can be severe, even if you only have a small amount on your person. Lengthy jail terms and even the death sentence have been handed down to Britons dealing in illegal substances overseas.
Don't become a victim:
Don't carry parcels or luggage through customs for other people. If it's in your suitcase, it's your crime.
Don't cross borders with people you don't know or even new friends - you could be detained as an accessory or accomplice to their smuggling.
Carry a doctor's prescription for any medicines you need and keep a copy of the original prescription with your important documents.

Diarrhoea
Who's affected?
Diarrhoea is slightly more common in young adults than in older people. The reasons for this difference are unclear. A lack of acquired immunity, more adventurous travel styles or different eating habits may play a part.
Attack rates are similar in men and women.
When to seek help
Diarrhoea usually strikes within the first week, but may occur at any time during the holiday - even after returning home.
If symptoms persist for more than 24 hours or if you develop a high temperature, consult a doctor.
Best treatments
The main risk with diarrhoea is dehydration. However, drinking water will actually encourage the loss of more salts from your body.
Instead, drink an isotonic solution - a quarter of a teaspoon of salt and three level teaspoons of sugar in one pint of sterilised water. This should be drunk at the rate of about a half to three-quarters of a pint every two hours or after each visit to the toilet.
Avoid alcohol, which leads to further dehydration.
Over-the-counter diarrhoea medicine can help if you experience griping pains in the abdomen.
Prevention
Always wash your hands before eating or handling food and after using the toilet. Also, keep your hands away from your face and don't bite your nails.

Skiing, like many other sports, carries the risk of injury. It's important you know what to do if someone gets injured on the slopes.
If a member of your party gets injured on the slopes, plant a pair of crossed skis above the accident site to warn other skiers and mark the location. Then call the ski patrol. At least one person should remain with the injured skier at all times.
Make sure the casualty is as warm as possible and take off their skis (but not boots). If there's any possibility of a neck or spine injury, don't move them.
Staunch any bleeding by applying direct pressure and elevating the limb, if possible.
Lie an unconscious skier on their side in the recovery position, ensuring their mouth is empty of snow and vomit. If they're not breathing, you'll need to resuscitate them.
A ski pole makes a handy interim splint for leg, knee and ankle injuries. For arm injuries, use a scarf or jumper to immobilise the limb.

In general, animals tend to avoid humans but they can attack, particularly if they're with their young.
Animal bites can lead to infections that may be serious, sometimes fatal. They can also transmit rabies, an acute viral infection of the nervous system. Rabies occurs in Europe and North America, as well as in the developing world.
In areas of endemic rabies, domestic dogs, cats and other animals shouldn't be petted. Wild animals should be avoided altogether.
If you're bitten by an animal, prompt treatment is vital. Treated early enough, rabies can often be prevented. Once symptoms develop, however, the disease is usually fatal.
If you or a member of your group is bitten by an animal:
Wash the wound immediately using soap, or flush with clean water for at least five minutes. Apply antiseptic, if possible, and cover the area with a dry dressing.
Seek medical attention immediately. If you need a rabies vaccination, the course must be started straight away.
Note the details of the incident and description of the animal. If it's domesticated, try to identify the owner. Find out whether the animal has an up-to-date rabies vaccine. Check if the animal becomes sick within a fortnight.
