I think it's wise to prepare and keep an eye on the news to know when to trigger your fight (or flight) plan. Panicking won't help.
As far as I'm concerned, it has reinforced my priorities, altered them slightly too. I think it's a good opportunity to reassess your objectives in life, if anything.
Anyway, off to bed early today, so I have more time to do what matters to me tomorrow. Can't wait to see my favourite muddy poney again :)
