At his age, there is no question that US President Donald Trump is dealing with health-related concerns. Observers have taken note of this, pointing out the warning signs each time the US Commander in Chief is seen publicly.
Now, some are taking aim at Trump's sleep cycle. According to researchers, the ideal sleeping time for any individual is pegged at seven to nine hours. However, there are claims that the 79-year-old may be getting only four to six hours of shuteye, likely following the advice of former physician Ronny Jackson.
