Ahh...The Paddock's general condescending attitude about ink. How about you do you and leave others to their own devices? Or do you want to hear my opinions on drinking cases of Bud Light and 3000 calorie diets?
First when I was 34 or 35, Celtic symbol for love with my wife's initials below. Followed by a Celtic cross, a trio of trinity symbols, caricatures of the first 3 dogs that were family to my wife and I with wings and halos, a 26.2 design for my first marathon because only pussies settle for car stickers, and a dio de muerte skull holding a rose. Probably got it at 43 or so. I want to get one for my ultra marathon, and another design as well. Just waiting for the right time.
My advice is - know your life and career. If you can't show it use your upper arms and shoulders. And use sunblock to protect them. And spend the money. Cheap is cheap.
