The field of ageing research is full of characters. We have hucksters claiming that cures for ageing can be bought and sold; prophetic seers, their hands extended for money, warning that immortality is nigh; and would-be Nobelists working methodically in laboratories in search of a pill to slow ageing.
We know we cannot underestimate the importance of emergency planning in our region, nor can we assume we'll have ample warning time. If an earthquake or terrorist attack hits, we won't necessarily have advance alerts or opportunities to double- and triple-check our plans.
The past speaks to us in a thousand voices, warning and comforting, animating and stirring to action.
Today, the technology is there to give early and normally ample warning when a powerful tornado approaches. When a tornado strikes, all of us are at risk.
Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts.
And the people who live in the southern part of my state do not have a secure environment. To wit, there are signs that the government put up that say, 'Warning. You are in a drug smuggling area and a human smuggling area.'
We need to make sure parents and coaches are aware of the dangers an on the look-out for the warning signs. Performance enhancing drugs are too damaging to young people for parents and coaches to not be involved.
One thorn of experience is worth a whole wilderness of warning.
Close to a billion people - one-eighth of the world's population - still live in hunger. Each year 2 million children die through malnutrition. This is happening at a time when doctors in Britain are warning of the spread of obesity. We are eating too much while others starve.
We must not constantly talk about tackling obesity and warning people about the negative consequences of obesity. Instead we must be positive - positive about the fun and benefits to be had from healthy living, trying to get rid of people's excuses for being obese by tackling the issue in a positive way.
