Can coffee improve your memory?

A couple of cappuccinos every day could reverse memory problems, according to reports in the news today. Initial results from tests at the University of Florida seem to suggest that two decent coffees each day might protect against the development of memory problems and could also reverse existing signs of memory impairment. There's more about the positive effects of caffeine on the BBC website, which says more research is needed before we'll know exactly what we should be doing... but meanwhile, why not ask for an extra shot of expresso in your latte?
