Old age consists of ages nearing or surpassing the average life span of human beings, and thus the end of the human life cycle. Euphemisms and terms for old people include seniors (American usage), senior citizens (British and American usage) and the elderly.

Old people have limited regenerative abilities and are more prone to disease, syndromes, and sickness than younger adults. For the biology of ageing, see senescence. The medical study of the aging process is gerontology, and the study of diseases that afflict the elderly is geriatrics.

The boundary between middle age and old age cannot be defined exactly because it does not have the same meaning in all societies. People can be considered old because of certain changes in their activities or social roles. Examples: people may be considered old when they become grandparents, or when they begin to do less or different work—retirement. Most developed world countries have accepted the chronological age of 65 years as a definition of 'elderly' or older person.

Norman Peter Lamb (born 16 September 1957) is a British Liberal Democrat politician, and Parliamentary Under-Secretary of State for Employment Relations, Consumer and Postal Affairs. He was formerly Parliamentary Private Secretary to the Deputy Prime Minister, Nick Clegg.

He is the Member of Parliament for North Norfolk.

Lamb was born in Watford, Hertfordshire, the son of climatologist Professor Hubert Lamb. He went to Wymondham College, then the University of Leicester, getting an LLB

After graduating from the University of Leicester, Lamb worked as a solicitor. He began to specialise in employment law whilst working for Steele and Co Solicitors (now called Steeles Law). In 1998 he wrote a book, Remedies in the Employment Tribunal: Damages for Discrimination and Unfair Dismissal, but any chances of a follow up or update to this book were put aside when Lamb was elected to Parliament in June 2001.

Lamb worked for a year for Labour MP Greville Janner in the early 1980s, working as a researcher. His politics were always in the centre ground, but a meeting with Shirley Williams in Parliament at this time, shortly after the formation in 1981 of the SDP-Liberal Alliance, spurred Lamb in to front line active politics and he was elected to Norwich City Council where he led the Lib Dem group until he stood down in 1991 in order to pursue his Westminster ambitions.
