Very sorry to hear that Ian. No one should out live their kids. It seems that Asbestos is one of those things which has no effect on some people, but it can kill from just one grain.
At age 11 I helped my dad lag our 12' steam boiler with chicken wire and Asbestos Meal. Mixing it up with my hands with water in an old tin bath and smearing it all over the boiler. I thought it was great fun at the time:white_frowning_face: Ron
Yes it is strange stuff. As you said it effects some people and not others. I look back to the 60s and blowing out brake drums for years, it doesn't bear thinking about.
