If we want to take action on climate change, then it makes sense to stop driving all over town (or across the country) to use a computer and the phone. Electric, autonomous cars are more efficient, but if we use them more (with our current sources of fuel), we haven't made a savings.
If we think that we need to address heath care... They say that 90% of all cancers are preventable. The enemies are smoking, drinking and obesity. I lost 40 pounds (2.5 bowling balls) through calorie reduction. I did not exercise. Exercise in not a requirement. The people who need to lose weight are typically ones that don't like to exercise. Losing weight was the hardest thing I did. Smoking, drinking and drugs can be fun. That is why we do them. But when you are doing them all the time, they are less fun and they are damaging. Everything in moderation they say.
So much manufacturing going to Asia is a problem. I can't fault Trump for trying to address that. Is it working? This is a complicated problem that I devote a lot of thinking to. I want to get elected and assemble a team to research it. I do not have enough time and resources to figure it out. I've written code for a CNC machine. I watch How It's Made a lot. The one on fiber optics is interesting. I'm up in the air as to whether our global trade is good or bad. I want to continue thinking about it.
Politics is more than campaigning, passing laws and funnelling money around. It's about coming up with ideas to solve a common enemy. It's about what we talk about at the dinner table. Your actions matter more than you realise. What we have in the future is a result of what people did in the past. If you overeat consistently, you may be in a position where you need to lose weight. If you don't lose weight, then you may get sick. If you don't get medical help you may die. No one's perfect. Do your best to nip it in the bud. The saying "it's never too late" isn't the whole truth.
