So, you forced your children to promise to take care of your retirement as you were to lazy for the last 65 years to take of your retirement yourself. Children should respect their elders. Yes, and you should respect those that have earned respect and those that earned respect are the ones who are earning a living and paying for your retirement. What about the parable of Jesus and the 3 servants that were given 5 talents to work with.

SINK ing it into the government is like sticking it into the ground and burying it.
And then watching inflation wear it down.
