Most fireplaces are only capable of warming the room they are in because there's no way to circulate the air.

You're trying to get blood from a stone.

I have read reports that Saint Paul is considering something similar but nothing has been circulated in writing. 

You can’t get blood from a turnip.

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”Good luck!

Basically a system that has a pump near the water heater that continuously circulates hot water so you have near instant hot water instead of waiting for it to come all the way from the hot water heater.

There may be an allowance because of your blood relationship.

A group of people together as it relates to a family unit has nothing to do with blood related.  

Quick stretch/2 min workout to get the blood pumping.

This can be prevent a lot of bad blood.
