cellphones

[David King]

Funnily enough this came up on PTNC recently

http://health.msn.com/health-topics/cancer/articlepage.aspx?cp- 
documentid=100211877&page=1


might be relevant to the discussion. Lots of websites discount the  
effects. Hmmm

Texting seems to be the safest thing! Hmmmm - interesting use of  
'safest' - I wonder what we mean by danger?
