This is a very complex topic, as the following talk suggests:
The main takeaways from this that I got are:
- Cancers for which sunlight deficit is a risk factor are orders of magnitude more prevalent than the few for which overexposure is a risk factor.

As someone who wonders on a regular basis whether the public has the right information to make informed decisions about health-related tradeoffs, I am curious… does the above strike you as surprising? What do you currently do regarding sun exposure, and are you likely to change anything based on the above? What do you think the overall message that reaches the masses is regarding sun exposure?
