Hello! I'm Mark Leithead ('Lee-theed'), Environmental Scientist turned Megalithic Explorer & GoldenEye 007 Speedrunner on N64, Xbox and Switch.
I upload 100% original high-quality videos of megaliths from China, nature and drone footage, investing information, speedruns of GoldenEye 007 & Perfect Dark on N64, Xbox and Switch (twitch.tv.Gygesz), climate change science and biology videos, yo-yo and spintop tricks, and much more.
I like to have fun on my channel and I upload videos in high quality 1080p widescreen 16:9 ratio.
