MOST of England will be covered by amber heat health alerts for the next three days. A Green health alert is for summer preparedness. The Amber alert we are currently experiencing has an impact across all areas of sobriety. Lunchtime drinking is mandatory, especially for homeworkers who are too often the silent victims of heatwaves. A Red heat health alert, which is yet to happen, would indicate a significant risk to life even for the healthily lagered-up.
