Two people from different generations who work in the health industry or have experience of the health industry discuss how technology has changed over their lifetimes.
Mr Terence Lewis is one of the country's pioneering heart surgeons. He recently retired but he returns to the building named after him at Derriford Hospital in Plymouth to meet heart surgeon Clinton Loyd, who is conducting cutting-edge surgery using minimally invasive techniques. Technology has moved on quickly in the last 50 years, but technology has also got to be measured against cost.
