Velma Lyrae spends up to 18 hours a day confined to a cage in her flat in Blackheath, London because she is allergic to modern technology. She can't use a mobile phone, satnav or WiFi, or even use a hairdryer to blow dry her hair. She suffers from an increasingly common condition called electromagnetic hypersensitivity syndrome (EHS) which means she cannot stand to be near electromagnetic fields. (Photo/Sipachina)
