I think you raise good points. I think there are lots of good things to have come from modern technology etc, I think the downside is that the way people live to day isn't very healthy.

Some things that concern me that I think is damaging health of our and younger generation (not in particular order) and just my opinion:

- mercury fillings
- smoking, both themselves and/or their parents
- excessive alcohol consumption
- cosmetics inc antiperspirants
- food additives, caffeine, aspartame etc
- fast food instead of fresh food
- car fumes
- hormonal birth control, both in young women and mothers of this generation who were amongst the first to use it.
- overuse of computers
- lack of exercise
- too much tv, not enough family and social interaction, which hampers mental development
- slip in social/religious standards, resulting in teenagers being sexually active from a young age, exposing them to risks of diseases.

I have to admit, I'm guilty of some of the above myself, but those are some of the things I think are damaging peoples health. I might be wrong, and not all these things do damage.
