F = G m1m2 / r2 . G = 6.67 x 10-11 N m2 kg-2 . m1 = 1 kg. m2 = 70 kg. r = 50 cm = 0.5 m. F = 6.67 x 10-11 x 1 x 70 / 0.52 . F = 1.8 x 10-8 N . Compared to the other forces acting, this is an insignificant force which is why you don't notice it. The reason why this calculation yields such small values is that the masses involved are very small.
