I was recently looking at what they can actually do to reduce consumption of petrol. It would be quite possible to build automobiles out of carbon fibre that would be just as strong, weigh 10 times less and consume 10 times less petrol.
I'm fine, but I'm bipolar. I'm on seven medications, and I take medication three times a day. This constantly puts me in touch with the illness I have. I'm never quite allowed to be free of that for a day. It's like being a diabetic.
