Well I don't know about against the law but in Social Care it is certainly frowned upon to refer to people as 'elderly' we have to call them (us?) 'older people'. But then again we are not allowed to refer to people as 'clients' or 'service users' any more either. We have to call people who use our services (or have them foisted upon them) 'citizens'. It's all bonkers to me. And I would definitely be sacked, hung, drawn and quartered for using that term. Bring on retirement!!
