What do you think is bad for us that we still consider “safe”

So we have heard about it and read about it, how previous generations did something that they thought was safe and normal, but was absolutely horrible for their health.

Example:

-Smoking on planes

-MDs suggesting cigarette smoking for headaches, stomach pain, and illnesses

-Cocaine in soda

-Heroine was a pain medication

-Women wearing radioactive paint as makeup when going out to night clubs

The list can go on…

My question is what are we currently doing that you think is detrimental to our health, but at this current day and age it is considered normal and safe. Something that you think 100 years from now other generations will laugh at us for ever doing it.

I’ll go first:

-Cooking our food in aluminum

-Chemotherapy
