This is inspired by a recent thread about sunbeds.
What things happen now, that in fifty years time we'll be horrified by in the same way that we're horrified by certain things from Victorian times now, or even things from the 1960s? I'm talking about both medical treatments, and products that are harmful to health. In fact asbestos is still a problem now if certain buildings are being demolished.
Smoking indoors is an obvious one - even now I'm amazed we ever went into a restaurant and specifically had to ask for a non-smoking table.
Sunbeds are already banned in Australia and Brazil.
Prednisolone is a nasty drug and I'd like to see it eventually fall out of use once something better has been invented.
