Blood test!

first thing tomorrow I have a blood test!
I hate them..my blood does not co-operate..it will stop mid-flow for no obvious reason...that is why I can no longer "donate" blood
To me..this is very annoying!
I know my Mum, and my sister are exactly same blood type as I am..maybe some of our children are!
If it ever came to it...I would give my blood for a younger generation to continue.
