(This one's not about perfume!)
I'm re-reading the strange and deeply wonderful "Time And Again" by Jack Finney, whose take on time travel is this: if you put somebody into the clothes of, for example, 1890, in a room authentically furnished and gas-lit as it would have been in 1890, with a view that is exactly what one would have seen in 1890, then a combination of self-hypnosis and "spirit of place" will send them back to 1890. When they get up from the chair they are sitting in and walk out of the front door, they will indeed be back in 1890. Or 1410, or 1972, or whatever date they're trying to get to.
I love this idea - after all, when are you ever going to be able to disprove it? You may be in a National Trust property where a Tudor bedroom has been lovingly recreated, but how likely is it that you'll be alone, wearing Tudor clothes and not seeing a National Trust van or gift shop outside the window?
I had lunch with my family last week, and was reminded once again that my grandmother and I share the same (somewhat naive) view, which is "Isn't it great that science hasn't yet disproved everything?" (ie ghosts, the afterlife, some form of deity, etc) - my stepdad, on the other hand, is a fervently rational atheist and was just starting to (mildly) use words like "twaddle" when I reminded him that of course he would say that, because he's an Aquarius.
