There really is a need for an adult Home Economics course online. Probably one for women and one for men. Not just about cooking, but going into things like:
cleaning
budgeting
sewing
home maintenance
savings
credit
car buying
renting and mortgaging
how to plan (using the Sun Tzu military method)
insurance
Hundreds and hundreds of hours of instruction here, but it would be invaluable to those who were never taught it.
Everyone of those listed is already available online.
