With me ... it's age! Humidity all along the east coast is awful in the summer time! I grew up in coastal Virginia but I've lived in Florida since I was 19. The humidity never bothered me when I was in my 20's, 30's 40's and even my 50's but now I'm late 60's and every year it seems to get worse; used to be in the summer I could be outside from 7 a.m. until 7 p.m. or later without any problem. Nowadays I can only take 20 to 30 minute increments ... I get overheated really easily so I have to be very careful.
