Birthday present

[Gambatte]

My birthday is approaching and "unfortunately" I already own all the desired or needed stuff for my hobbies, cycling, running (been injuried for months, but this is another story...), or mountains (nearest mountain 1000km away, also another story...). I'm not on useless overpriced electronics like Garmin GPS running watch.
Of course I fancy a new carbon bike (not really needed) but I just feel morally wrong to splash out 4k just because bicycles are cool.

What to suggest to my girls for present?

A tree. I'm a green taliban (and proud of it) and I feel trees in my garden are never enough. Even more so as the latest pear tree at front died (immediately after I planted it, no idea why). But maybe best waiting until early spring for planting new trees....

A magazine. I love reading politics and international affair. My fav mag is The Economist. But at 275 eur/yr is expensive. Otherwise the NYT, but the very fav but still great, and now only half euro a week.

Any suggestion?
