Is it normal to get light headed & really pale after exercise?

Recently I noticed that I have been getting light headed everytime I work out... maybe it's cause I'm getting old but even my buddy said to me during one of my sets "hey man... you look really pale" I took this picture at the end of my workout sesh and it doesn't do it justice. I was pale like a ghost moments before I took it.

What do all you think? This is new to me
