I have a very quick comment.
Mining is a risky business, oil and gas is a risky business, and when they got started, there were flow-through tax credits to help encourage people to put money into those. That's how they really got their start in Canada.
Biotech is a long-term, risky business as well. It has never enjoyed the same type of support from venture capitalists, and venture capitalists have never gotten the same types of breaks as those investing in mining and oil and gas.
