An exercise band, a ball and a seed bag belonging to long COVID sufferer Jorge Martin, 44, the head of a higher-education association, are photographed through blue plastic, in Ansoain, northern Spain, March 17, 2021. The photograph was taken through blue plastic to visualise the effects of long COVID. Martin has been off work for more than a year due to long COVID. He developed double pneumonia when he got infected with coronavirus during the first wave of the disease. He has been battling with cognitive difficulties and a long list of physical problems ever since. "I would not have pictured myself at my age using rehabilitation tools, but I've welcomed them because they help me with my physical aches and provide me with some relief from the distress of looking at the calendar and realising that a year has gone by and I'm still not recovered," he said. Martin is worried about the toll the disease is taking on his job. "I forget the names of family members, even my own license plate. The other day, I was trying to write something down and I realised I was writing again what I had written two days before. My job is intellectual, what's going to happen if this gets worse?"
