Lia will turn three on December 28th. She doesn't walk independently – she crawls a lot, of course – but she's close to it, and although she communicates in her own way – she points and makes herself understood – she still doesn't speak beyond a few words. She's had multiple tests, and she's being monitored by specialists of all kinds, but they still haven't found the disease that explains the causes of this global developmental delay, although they suspect it could be a rare disease of genetic origin, explains her mother, Laura López Crespo, 39.

At 25, Germán's first gray hair appeared, and by 30, his hair was already completely white, but he didn't think anything of it, attributing it to stress. Since his father died of pulmonary fibrosis and he bears a strong resemblance to him, he's always taken care of himself, exercised regularly, and has never "felt ill." Even so, when he was 43, he developed bronchitis that didn't completely clear up. He saw various specialists and was finally hospitalized at Vall d'Hebron, where he underwent numerous tests.
