The only thing that bothers me is crawling through small tunnels...worse if there's water through it! I'm forever under floors & it's never bothered me but about a year & a half ago, I was running a power feed in from a CU to a cooker & the further up the house I went, the shallower it got. It got so tight that my back was touching the ground while me chest was touching the underside of the floor. I was a good 20m away from the opening. I panicked & froze up. Never had that happen before. I eventually got coaxed out after calming me down.
Everything else looks great to me & it's all about team work
