Scotland has been part of the United Kingdom for more than 300 years. This fall, that could change. In mid-September, a referendum on independence will determine whether Scotland breaks off from England, Northern Ireland and Wales to become a sovereign nation.
Scotland's largest city, Glasgow, is ground zero in this debate. The East End of this city is poor and run down, with some of the worst health figures in Europe. Men here are expected to live into only their mid-50s, some 30 years less than in wealthy areas.
