And practice what they preach.
Have just clocked the overweight nurse that did my recent health check, smoking like a chimney and munching on a chocolate bar!
This is somebody who sat there and lectured me on cutting down on carbs, eating oily fish once a week, not smoking and to drink in moderation.
It's a bit rich!
We expect fitness trainers to be fit and lead healthy lifestyles.
So, surely somebody who's job it is to advice people on healthy lifestyle choices should also be fairly fit, of a decent weight and not be puffing away like a chimney.
How can we take their advice seriously otherwise?
Or am I being unreasonable? (I know they work long hours and there's a lot of stress), but surely the ones that are doing the health checks and doling out 'healthy living advice' should be an advertisement for what they're saying?
