At about the age of 65, many people lose some sense of taste and smell, and their appetite suffers. Try stimulating it with a variety of strongly flavoured foods, such as curry or chili con carne. Vary the texture, colour and temperature of your food, this may compensate for the lack of strong flavour.
Savor each bite. Chewing slowly and moving the food around in the mouth before swallowing increases contact with the taste buds and, through the hack of the mouth, with smell receptors in the nose.
