I have just finished watching trash journalism A Current Affairs and they did a report in which a professor did tests that show that exposure to radiation through use of mobile phone can cause brain cancer. This has kind of worried me, but of course I've got to explore the issue first before I make a decision. This worries me because although I don't use the mobile phone much I do keep one in my right pocket all the time and this right pocket is right next to my reproductive organs. If the mobile phone is indeed harmful then it is likely to harm my reproductive organs, rendering me impotent (see Mobile Phone Use Linked to Sperm Deaths).

It is difficult because one side says that mobile phones do cause cancer while another side says it doesn't while many say that it depends on how you use the mobile phone. What do I assume first and where does the burden of proof lie? Do I assume that mobile phones do
not cause cancer and wait for sufficient evidence to suggest why (this is the classical assumption of the null hypothesis) or do I assume that mobile phones do cause cancer and wait for evidence that says that it doesn't?
