Back when I was 6, in 1983, my uncle who worked in the oil industry told me about global warming.
I could totally have been a real radical environmentalist, but I was 6.
A second time around that talk would have an impact, and with some foresight for the next 40 years. I think no one would be surprised if I devoted everything to fixing global warming - they might be surprised at my success in the stock market.
But you can only use them on new wounds. If one fails, for example on a finger abrasion injury (the only place I have ever had those fail) you need to replace it with a different type of dressing.
They do stick better than any of the alternatives I have tried and that provide the best healing environment
