Essentially, he was suggesting by implication not to ‘waste people’s time’. He didn’t name their roles, but the natural and fair extension to his comments about checking your own blood pressure instead with the watch, directly linked to the previous time wasting remark. So it wasn’t wasting your dustman’s time. Now, if this watch is not pinpoint accurate, and gives you say, a normal blood pressure when the reality, with dedicated medical blood pressure taking equipment, gives you a high blood pressure result instead, by not wasting people’s time, you potentially leave a serious condition undiagnosed. WASTE PEOPLE’s TIME!! Get your blood pressure checked by a GP or a nurse. Many GPs had two years off from face to face consultations during Coronavirus. My wife was misdiagnosed over the phone by one and subsequently died from sepsis. ‘Waste’ their ****** time, and get yourself checked properly.
