Antibiotic resistance is serious business.

Also, what is not often said is the immune system gets compromised as men's bodies deal with STDs and recover.

Just because there are drugs to fight STD infections and recover from them does not mean total success, because the immune system becomes weaker and non-STD infections become easier to pick up.

Ditto with vulnerability to cancer, where in reality cancer is not an infection (not a virus) but the body's failure to deal with creating defective cells......

In summary, people who have been sick and recovered do not have the same quality immune system as those who hardly ever get sick when other infections/diseases knock on their doors.
