Spring is the ideal time to start walking more than in the past 6 months. Flowers all around and sunshine invite to go outside. It is so good for our health. Our mobile phones count steps for us so it is easy to reach targets you set yourself. No pressure just fun. Chose a nice surrounding, city or landscape, and the benefits will accumulate rapidly. Improving sleep afterwards is just one of the many side effects. No excuse on the long Easter weekend with bank holidays as well. Anyway, that is what I do. For our health every stride counts in the short run and even more so in the long run. Hence, let’s go. Take a few photos to look at afterwards as your special self-made reward. Cheers and Happy Easter or seasonal greetings. 
Speculation bubbles
Learning about bubbles is exciting. As kids we jump in the air to burst bubbles, as adults we are delighted to taste sparkling wine. It is easy to know that a bubble has burst (ex post). Many examples can be quoted in economic and social history on this. When bubbles burst hitting many persons this becomes an issue of political economy. Are we just behaving like “apes” with basic “animal instincts” as suggested by “Jan Bruegel d.J.”? Tulip mania is a part of European history and Bitcoin mania the most recent example of a bubble-like development of a specific market. How about creating your own currency. Here is how to do it. How to get drawn into a bubble can be physically experienced at Floralia-Brussels until 5.5.2019. You won’t look at tulips the same way afterwards.
