Yes, this was me.
In the comments a number of people think that life in the past would be a piece of cake because we know more science and math. Here is the reply I left in the comments.
For everyone arguing that knowledge of math and science is the key to success - I think you are underestimating the role of class in these times.
You will probably not know enough conventional wisdom to pass a sniff test in any time before the early 1900's. Also consider how the mainstream viewed certain types of discoveries - eg Galileo.
I don't think that you would be able to burst onto the scene and proclaim some hugely advanced truth - they wouldn't be able to understand it. To even have a shot you would have to walk everyone through the incremental steps to get you to the 'ah ha' moment - and that is only if you can ever get anyone to listen to you.
I personally don't think that a modern American would be able to deal with the vast amounts of physical labor that would be involved:
1) There is no in door plumbing or running water.
2) Electricity isn't available - everything is done by hand: cleaning clothes, carrying water, etc.
3) You will probably not be able to afford meat, at least not much - is your metabolism capable of handling an all starch diet?
4) You will need to walk everywhere you go.
5) You will need to deal with all of the aches and pains we pop pills for today.
6) Pollution is going to be much worse - what effect will that have on your health?
