This is a toughie for me. I know we need sunlight to be healthy but Gracie, Simon, & I have such fair skin. And, to really muddy the waters I was just reading some new research and it stated the SPF is only for UVB and it is primarily UVA that causes cancer. Also, UVB is stronger from 10-4 but UVA is just as dangerous in the early/late hours as midday. Also,
it is now believed that UVA causes skin cancer by supressing the immune system. Yet another reason to avoid sugar--sugar suppresses the immune system, too.

Gracie is asking to nurse (for bed) so I have to go now. I will try to post more links later.
