I can't answer the OP question, as it depends upon the weight and fitness of this normal person.
Here's my two cents though: 11-32 is a huge spread on a road bike, I don't know how many cogs you have but you're going to have some large gaps between gears in there, with cogs you might wish you had for long rides. If you're considering this combo (50-34/11-32), you should really be looking at getting a triple crankset. You get a wider gear range and smaller gaps between gears. The inner ring on my triple is a 30t which I think is pretty typical. My cassette is 13-26. So I'm getting about the same low gear as your 34/32 but with a much tighter cassette. 30/26 lets me spin up just about anything (I live in a very hilly area), and the 13 with my 52t big ring is tall enough to where if I spin it out I'm fine just tucking and coasting.
