I do think my life is richer for this knowledge - and i wonder how rare it really is?
It's entirely normal in my larger family, which contains lots of farmers and also academic botanists and herpetologists and the like. There were a lot of outside walks as a child, and if we saw something we didn't know, we would look it up when we got home - and we had the books to do so.
But I also discovered at work, when we went on lunchtime walks round the site, that me saying things like, "oh, the orchids are out!" or, "doesn't the loosestrife look lovely when it's flowering," or pointing out particular birds or fungus is just going way over their heads.
In my new job, I'm joining a wildflower walk on site next week, led by the local wildlife Trust, but I suspect that will be preaching to the converted, those who turn up. Should be good, though. It's the best time of year, and there's lots out, like pyramid orchids.
