I like HANS and the advice he gives, but you should never 100% rely on someone else to run your life or make decisions for you.
yes, you should seek out informed medical opinions, but they don't have to live with the consequences of those decisions - you do.
do your own research, form your own opinions, ask why they want to do someone or not do something, push for answers that you understand. you are the customer, this is your body, your life. there are no do overs. sitting in passenger seat is just not an option.
