If you really want to feel empowered, you could start by writing to your local MP and local councillors about the chronic lack of capacity in the NHS, particularly ICU compared to some of our European neighbours. After that you could try to rally other people to do so, maybe join groups with similar ends, create your own, or if you really want to make a difference consider actually moving into politics, or at least supporting someone who is.
Or you could continue to signal your virtues by trying to convince others that you wear a bit of cloth over your face "for the good" of others.
