Stand up in the presence of the aged, show respect for the elderly and revere your God. I am the LORD.
(Leviticus 19:32)

I'm a baby boomer and many of my friends have faced, or are now facing, taking care of their aging parents.  It's tough to watch those we love losing their health and independence, especially if those we love aren't able to recognize their weaknesses.  They may be angry, belligerent, and just plain ungrateful for the efforts being made to keep them safe and comfortable.  We have to remember what they did for us, the sacrifices that they made for us and now it's our turn to repay them, easy or not.  God commands us to take care of our elders, showing them love and respect.  It really isn't much to ask and it should be a pleasure, regardless of the challenges, to assist them during their final years on earth.
