LANGUAGE
This is your ability to use a system of letters and words to express ideas and to communicate effectively, both verbally and in writing.
Vocabulary tends to stay well preserved with age, but we can increasingly find retrieval (getting the words out) more difficult.
You know your language skills are starting to drop when you find it increasingly hard to come up with the words you want to use when you want to use them.
Studies show language exercises really can help you swiftly find the word that is dangling tantalisingly close on the tip of your tongue.
