Women give more blood, organs and stem cells than men, though the UK most needs more male donors. Men have real advantages as donors: they can give blood every 12 weeks rather than 16 because they generally have higher iron stores, and their plasma and platelets suit many transfusions. Research points to motivation. Women report a stronger warm glow from giving, a feeling linked to the hormone oxytocin, which is also tied to trust and generosity in experiments. Men are more often moved by heroism and personal health benefits, and recruitment events see more squeamishness among young men.

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.
