i have no idea lol

They aren't. Java uses the (safer) idea of references instead of pointers.

It depends on how you look like it. 100 years ago, you didn't have the ideas of bacteria and other germs. So in that way, today's food is much safer. But in the idea of safer as in, 'fattty', it's not safer. 100 years ago, sugary, packaged foods were not around. So food today is not safer for your cholesterol, but safer for colon:)

bad idea- just buy lowering springs. it's alot safer for everyone!

Statistically the larger the vehicle the safer it is. Government safety ratings will give you a good idea of how safe a particular vehicle is.
