Autism is a neurological disorder thought to be caused by mutant alleles of one or more genes in an individual. scientists had been wondering why the number of children diagnosed as autistic has increased dramatically in the last decade, from 1 in 500 in 2002, to 1 in 88 in 2012. researchers now think that they might have found at least part of the men are fathering children at later and later ages. a paper published in the journal nature in 2012 showed a correlation between paternal age and the incidence of autism; the age of the mother was not a factor. how does this observation provide a possible explanation for the apparent increase in the rate of autism?

That would be a working theory.

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
