business doesn't always tell the truth

i know that the kids don't like it if i wash something (clothes) in hot water but when i was growing up, hot water was the way to go.

i found this article the other day which makes the point --

 http://www.dailymail.co.uk/health/article-2050239/How-washing-machines-familys-health-risk-Low-temperatures-mixed-loads-spreading-dangerous-bugs.html

it's always reassuring to be validated.
