Hanging with friends - good-ish for longevity. Family? Not so much.

So, if you need another reason to avoid those painful family gatherings here it is - they might literally be killing you little by little.

But spending time with family members is actually worse for your mortality, as they can add stress to your life.

Dr Eran Shor, who led the study, told the Independent: ‘Our findings show a minimal effect of social contact frequency on mortality and call into question interventions and clinical advice that simply seek to increase one’s social contact frequency’

Researchers at McGill said that while the majority of existing studies reported a positive link between increased contact and longevity, their own study found only a very moderate effect when considering other variables, including age and scoioeconomic status.
