I have had some pretty bad sunburns (blisters) so skin cancer is defo a concern.
I spent my childhood eating a lot of convenience foods (potato waffles, fish fingers etc).
I spent 5 years in the RAF drinking ridiculous amounts of alcohol and takeaways several times a week. Oh and mess food.
While in the RAF I worked with dodgy oils, fuels and lubricants daily which were carcinogenic.
But I don't think about any of that stuff tbh!
