if I'd been born 100 years earlier, I'd have died much younger than I am now, even before I got carted off to the Somme. Antiobiotics saved my life.
The extra money in those days would have allowed you to employ people to do things you can now do much more quickly on your own (delivering messages to relatives rather than phoning them, or hunting through the British Library rather than clicking on Wikipedia), so there might not have been much net gain. More rooms in your house, but harder to heat and light them (gas lights and no double glazing?).
However, moving to a future where £40,000 is still enough to buy a gel that makes all my teeth grow back and my stomach vanish is quite appealing. Though of course I might perish in an interglactic war between Mars and Zorg.
