There are pros and cons with both ends of the human age, that's obvious that's why it's necessary for as many people as possible to vote. 16 year olds granted will have much less life experience than someone who is 80 but equally they won't be likely to be suffering from dementia either. I'm not suggesting that anyone over 35 is a shambling wreck, but a reasonable proportion of pensioners have some cognitive impairment, dementia, Alzheimers etc ( 1 in 14 over 60 and 1 in 6 over 80). THAT is a huge number of people able to vote and by some people's reckoning on here more equipped to vote than someone of my age, and frankly that's crazy.
