You sure can John and I look forward to reading your hubs.
You can help the HubPages community highlight top quality content by ranking this answer up or down.
As the others have said, of course you can. I haven't seen a lot of hubs on the topic, so you may have found a unique niche that will get you a lot of views.
Hello John, Yes you can write about these topics. You can write anything that does not infringe on the terms of service on Hubpages. Good luck my friend!
