Bloody hell that's a bit patronising. I'm 55 (OK not 70) but went solo on my sixth flight after 4.30 and did my PPL in the 45 hours. In fact I was ready long before 45 hours. I don't feel the need for a safety pilot and my medical was AOK. I have my own teeth, still enjoy the delights of carnal passion and have a full head of hair.
Get some in, as the old saying goes.
