I have 2 stents also about 2010, before that i had a thrombosis in the lung and lost a 1/3, I'm almost 63, diabetic and slightly over weight, a smoker too, its not as frowned apon here in spain.
One thing is certain, if i get Cov-19 I'm a goner for sure so I'm volunterily isolating myself even though its also forced here still, once the isolation is relaxed I will stay in isolation for a few weeks at least unless a vacine is available. Spain is one of the worst places to be right now due to goverment reaction being 10 days later than it should have been and the deaths reported is far from the truth. If your a pensioner or retired its a good excuse to lock yourself in your workshop and have the least personal contact possible just in case.
To make things even worse my wife is a butcher and has worked throughout the whole deal and in contact with hundreds of people daily.
Stay safe, stay at home if possible.
cheers
Derek
