DALLAS: In a small town, about 30 minutes drive from Amsterdam, a woman in her late 80s is having her hair done. She sits in silence as the hairdresser talks about her day and gives her a blow-dry. It’s unlikely she remembers what the word “haircut” means – she’s no longer able to communicate verbally – but the hot air, the sound of the blow-dryer and the feeling of hands running through her hair are familiar and comforting.
