Do Laptops and Computers spoil your health - eyes and hairs?

Hi,
Call me Penpal for now, and a good one at that.
I originally come from India, but I consider myself to belong to the world
and having traveled globally, I prefer to be nationalized as world-citizen instead of mere Indian according to rigid earthly concepts.
Nice to know you all.
I am seeking some good quality healthy and diet-conscious friends worldwide.
I am not looking to lose or gain weight, just maintain it.
Any ideas about how to keep your eyes and head-hairs healthy for men?
What types of food can some of you diet-conscious experts suggest?
Let me know more about you.
Keep sugar to minimum, keep citrus to maximum, keep sunlight to moderation, keep computers and gasoline to minimum,
keep your carbon footprints to a minimum, save your planet as well to save your health.
Do you know that laptops and computers can have an unhealthy effect not only on your eyes, but also on your head-hairs?
Let me know if you have more knowledge about these matters.
Early to bed early to rise makes a man healthy, wealthy and wise; however, computers, laptops, and internet change all that!
Have a nice day.
Write if you wish.
