Get some candles ready; this Saturday night (29 March) it's lights out at 8pm for Earth Hour.

Last year over 2 million Sydneysiders spent an hour in the dark to throw light on the issue of climate change. The word is spreading, with two dozen cities signed on to switch off.

So, it’s Easter this weekend. And for most of us that means four days off. And chocolate. But, like the sugar-high from eating chocolate eggs, rabbits, bilbies, anything as long as it’s chocolate, the post-holiday vim is over all too soon. The following Monday it’s business as usual and it feels like a year since you had a holiday.

Life coach Kate James says: ‘One reason for people losing their holiday mojo so quickly is because they undertake a holiday that doesn't fulfil them personally. People should consider destinations that offer interactive holiday experiences such as being outdoors and in wide open spaces.’

Another option is to make a holiday out of staying home. Says James: ‘baton down the hatches. Don't see anyone, just do all the things that feel like they are restful for you.’ And why not send your friends postcards from home, visit tourist attractions that you’re curious about or take a train to a suburb you’ve never been to and explore.

American artist Chris Jordan proves that there's more to see if you make time to take a closer look...

It’s eel season. While their smoky eely goodness is available in Japanese restaurants year-round, traditionally Aboriginal groups recognised March as eel season. It’s about now that fat eels begin their spawning migration (so are more easily trapped).

Something of an enigma to Western science, much about eels remains unknown. We know they spend their lives in fresh water. And that somewhere between 10 and 20 years of age their bellies turn silver and their eyes widen – sure signs they’re about to embark on a 3000km migration to spawn. It’s thought they travel to somewhere between Samoa and the Coral Sea, where they spawn, then die. The baby eels are then transported back to the estuaries on currents. During this year-long journey, their physiology changes: adapting from salt to fresh water, they eat for the first time and, importantly, take become male or female.
