BY the year 3000, the average human will be 6½ft tall, have coffee-coloured skin and live for 120 years, new research predicts. And the good news does not end there. Blokes will be chuffed to learn their willies will get bigger — and women’s boobs will become more pert. But there is also a downside, the study suggests. We will be more prone to disease and physically weaker because of our increasing reliance on technology. The predictions appear in a new report by evolution theorist Dr Oliver Curry, of the Darwin@LSE Research Centre at the London School Of Economics.
