An unexpected occupational hazard...

This from Yahoo! News:

Scientists from Maastricht University found that burning candles and incense in church can release dangerous levels of potentially carcinogenic particles, according to research published this week in the European Respiratory Journal.

The article goes on to suggest that average churchgoers might not be at significant risk, but to express concern for clergy, choirs, and others whose church attendance is more regular. The scientists are calling for studies into whether worship leaders are more prone to lung diseases than probability would suggest.

So there's a good reason to go to Christmas Day worship services instead of the beloved Christmas Even candlelight service! ;)
