For Mutley and some others.It’s OK not to understand, very, very few will.
You won’t have the full set of data available to you nor the specialist statistical analysis programs to organize and interrogate the data. You also won’t have the statistical, analytical capability to interpret the data. Then there are the medical and scientific experts who compile and asses the data at post-Doctoral level. They have access to a huge wealth of published and unpublished scientific papers and reports as well as direct connections to their peers are around the world so they have access to the very latest, yet to be published, data. Finally you won’t have the capability to interpret this knowledge at Professorial level and provide expert assessment and advice.
Taking discreet tiny sets of information you have discovered on social media, the internet or from friends and family doesn’t equate to the above.
All you have to do it accept that our medical experts are acting in our best interests and to follow their advice. It’s hard for some, scary for others, but have faith in these experts who have dedicated their careers to the benefit of us all.
