Yeah but think of all the fresh air, exercise and adventures you would squeeze into those 30 years! If you subtract all the time wasted sitting in front of a computer or television, the average lifespan of a modern first-worlder is about 18 weeks. I say let's all bomb each other back to the Stone Age and learn to live again!
We would still lose all our teeth at 30 in this modern day an age due to sugar consumption but for the wonder of dentists. They reckon soft food consumption causes overbites too, which usually requires years of dental appointments to fix.
Imagine going your whole life without a visit to the dentist!
Your nearest and dearest would chew your brontosaurus steak for you and spit it in your mouth, unless you were a twat, then they'd leave you to die, much like kids today who think your a twat for pushing them into nursery, then school, then uni, then a job and sometimes marriage.
Early man/woman life is probably like life for people who've retired with a full state pension and spending money. Wonder round aimlessly, eating, drinking, sleeping but without aching joints, memory loss, incontinence pants.
