Overseas health insurance cover might be something to for older people to consider.
According to Nancy Morse, senior scientific officer at health supplement research group Efamol, people over 50 are now "more health conscious than ever before".
However, she added that research from Efamol has found that older people often have regular short-term memory issues.
Indeed, the survey found that 71.3 per cent of over-50s admitted to doing things like walking into rooms and forgetting why.
To improve cognitive function, she advised taking part in mental challenges everyday, like crosswords, quizzes or Sudoku.
"All these pasttimes will keep your brain active and stimulated. In addition, in order to function properly, the brain relies on oxygen that is carried in the blood, so regular walks in the fresh air and light outdoor exercise will all help boost your oxygen supply," added Ms Morse.
