Letter: Starmer and Trump share short sleeper syndrome

Pilita Clark identifies the ability to work phenomenally hard on “ridiculously small amounts of sleep” as Sir Keir Starmer’s superpower (Work & Careers, July 1).

Short sleeper syndrome is an inherited genetic trait where an individual sleeps little, without suffering from daytime sleepiness or other consequences. The condition is entirely natural. For good or ill, Starmer shares his superpower with Wolfgang Mozart, Margaret Thatcher, Barack Obama and Donald Trump.
