Lyudmyla Mozgova holds tools as she checks connections of a power storage and extra batteries for the respiratory unit and medical mattress of her husband Valentyn Mozgovy, paralysed by amyotrophic lateral sclerosis (ALS), before a blackout period in Kyiv on January 21, 2023. - Adapting to power cuts triggered by Russian strikes on Ukrainian energy infrastructures was a matter of life or death for Valentyn Mozgovy, who cannot breathe without a ventilator.
