This is great initiative by you @crypto.piotr and congrats to @fucho80 for the baby.
As you asked if our kids will take care of us after 20-30 years then. I think this would be difficult and looking at the current scenario when we can see many kids who are not even interested to stay with their parent so after next 20 years things will not be like this. I just think that we should do our part and should not expect much from the next generation. If they do then its good but if they dont then life will be a challenge for sure.
Thank you. Resteemed and voted.
