No air conditioning would be my undoing. I hate heat and humidity.

On a more serious note, how about no modern medicine? The germ theory of disease was nearly 250 years in the future.

Herbal remedies, country stuff I guess... yeah you're right. A lot of the real colonists died from disease. If nothing else, it makes you appreciate what you have now.

Heat and humidity--plus several layers of clothes. Clothes that don't get washed after every wearing--chemise, corset, petticoats (usually two or three petticoats, frock, apron. Cap on your head to try to keep the grease and smoke and dust out of your hair...no screens on the windows.

Very uncomfortable. Even with an army of servants--far less comfortable than our society.
