No, please don't tell me about planes ... I don't like flying anyway ;)
This way we are all the same ... when we are young we don't think, that we could get old one day, and for example, when we read in the dark without an appropriate light that our eyes will get bad ... or that smoking damaged our lung ... and so on ... one day we all get the bill - my back and my neck hurt and I can not read a newspaper without my glasses because sometimes I sat in front of the computer for up to 20 hours a day.
