High UV Levels? Good For The Garden!

So I head on the news last night that UV levels would be through the roof (or should that be atmosphere?) today. I shall have to slap on the factor 50 before I step foot in the garden this afternoon. Before that it's off to my obligatory morning on site helping those delightful trainees as I continue to hand over my role/share my lifetime of knowledge, and just generally potter about a bit... Winding down is never as much fun as it ought to be!
