10km long run Started at 11am and it was already hot and humid. Just a good example of how much heat affects performance. My heart was racing even when I jogged slowly. I guess my body was trying to lower my core temperature by pumping more blood. Anyway I saw a TED talk video which says that running can help generate new brain cells. Google: "running brain cells" if you don't believe me So double tap on the photo above if running have made you smarter Thank you genius 😃 #runner #running #nikeplus #nikerunning #slowkidsofinstagram
