p.s. I’ve been sending out a newsletter every week for the past 7 years looking in depth into a topical health issue. If you’d like to get these insights, I’d really appreciate your support. You can get them straight to your in-box from less than £1 per week, plus get access to all past issues, my PhD thesis and more… You can sign up here. Thank you for helping me to stay independent :-)
