Are we living in a toxic environment? The experts at Canyon Ranch ask us to consider these facts:

• The EPA estimates that 4.7 billion pounds of toxic chemicals are released into the environment annually.
• It's likely that 25 percent of the U.S. population suffers from some level of heavy metal poisoning.
• Fourteen pounds of food colorings, additives, preservatives, emulsifiers, and flavorings are consumed per person each year.

Toxic? Maybe. At minimum, though, we are living in a world filled with chemicals, pesticides, additives, preservatives, antibiotic and hormone residues, and heavy metals. Whether consumed, inhaled, or absorbed, our bodies soak this stuff up. In order to reduce the load, and the toll it takes it takes on our health, there's something we can do. We can eat clean. Here's how:

There are all sorts of gifts for dad on Father's Day -- shirts and ties and books and coffee mugs and golf balls -- and many of us have already spent money on the stuff we can wrap up and deliver or mail off to dad on this special day. But some gifts -- the ones we can't wrap up -- have an appeal that is priceless because they focus on the moment, they build relationships, and they promote mental and physical health. And here are just seven simple but everlasting gifts to consider sharing with dad on this Father's Day.

I was hospitalized twice last year for chemo-induced fever and low blood counts. My first stay came at a busy time -- the hospital's oncology floor was full and there was no space for me. So I was admitted to the bone marrow transplant unit as an overflow patient and suddenly -- even in my very sick and compromised state -- I became the healthiest person on the floor. My white blood count was 700 -- sounded pretty bad to me -- but some of the patients staying on this floor with me had no blood counts because in order to receive a transplant, their own bone marrow is completely depleted in order to prepare for new bone marrow. Patients on this floor are considered pretty healthy when their counts reach 500. I was considered sick and was hospitalized at 700. Adults and children on this floor stay in rooms behind glass panels and with special -- and loud -- air flow systems that push germs out of the room. Visitors must wear gowns and shoe covers and must wash their hands before entering the rooms. Patients might stay on this floor for months at a time, receiving chemotherapy and preparing for their eventual bone marrow transplants. Some patient rooms are decorated and arranged just like home. Parents prepare rooms for children with play areas and craft areas and television areas. This floor is home to many sick children -- and this is what affected me most. For my five days on the bone marrow transplant unit, I gained an up-close and personal look at what many parents and children encounter when cancer derails their lives. It was so much more than I had to encounter. It must be quite an undertaking to prepare a child for this experience.

I picked up a coloring book the day I was discharged and walked off this floor and back into my own life. It's a coloring book that comes from The Leukemia & Lymphoma Society and is made by bone marrow transplant patients for children preparing for their own transplants. There is a poster for children to color and hang on their hospital room walls that says I Will Get Well, there is a page that terms chemo and radiation as Laser Rays and Guard Dogs and pages that help children visualize happy moments -- like playing a favorite sport or activity and jumping rope in the warm sunshine. This book reminds children that it is okay to cry and it even includes a prescription: Make sure you get at least one hug every day!

The overall message of this coloring book, which is stated in writing is, "A good attitude does not mean being cheerful all the time; it just means that you know that this is necessary to help fight your cancer."  Well said. And something I will always remember.
