Hello ! so interesting to discover the backgroud of many members ! Scientific, artistic, technical etc... Great topic !
As a kid my favourite hobby was mixing funny products to get funny results (for example mixing fertilizers and sugar to fuel cardboard rockets,...still got my hands, legs, eyes etc... but it is a miracle...), and that was really scaring my parents...Then my dream was to become an airliner pilot, but an eye deficiency stopped that dream.. and i became a Physics and Chemistry Engineer in 1991 (back to funny mixtures).
My first job was to visit oil production fiedls around the world (on and offshore) to design chemicals for crude oil processing (viscosity modifiers). It was a great job, globe trotter style, discovering many countries and people, trying to learn some words of different languages, trying to learn how to write with different alphabets etc... After 911 2001 security conditions in different countries began to deteriorate, war in Irak in 2003 (I was working in Koweit at that time, and I realized that the black smoke I saw on the other side of the Irak Border was not only a TV breaking new), the fact of travelling really too much and not having time to see my children grow up made me change my job plan, and from 2004 I have been working in France, in different industries (asphalt, concrete, and now varnishes and paints). I am currently the operations director for a company that produces coatings for wood, for industrial applications (kitchen cabinets, coffins, flooring etc...).
Now my kids are away from home, everything is OK for them, they have their job, their flat (but no fish tanks haha) , and I am quietly waiting for my retirement 🙂
As a chemist, i enjoy reading long threads on pH, KH, solubility, conductivity etc... and after reading, I go back to my fishtank and say to him: hey man, you know that the best to do is not adding this and that to the water to monitor pH and KH and GH and... no, the best is.... time ! 🙂 Time will tell 😉
